if you are given two coordinate points, you need to first find the?
Answer: First you need to find the first point on the coordinate graph..which would be x then y. Remember run before you jump.
Step-by-step explanation:
The first point on the coordinate graph, x, must be identified first. Remember to run before you jump.
What is the coordinate points?A set of variables that accurately depicts a position. On a graph, the first number represents the distance along, and the second number represents the distance up or down. For example, the point (12,5) is 12 units down and 5 units up.
A coordinate plane is an organizing structure for graphing and describing lines and points. The coordinate plane is made up of a vertical (y) axis and a horizontal (x) axis. The coordinate plane is divided into four quadrants. The origin is where these lines intersect (0, 0).
A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x, y).

write an equation in point slope form of the line that passes through the (0,1) and has a slope of -3/2
Answer:
y - 1 = -3/2(x - 0)
Step-by-step explanation:
trust me
The equation of the line in point-slope form is y - 1 = -3/2(x - 0).
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that line that passes through the (0,1) and has a slope of -3/2. The equation of the line will be written as,
y - y₁ = m(x-x₁)
y - 1 = (-3 / 2) ( x - 0 )
Therefore, the equation of the line in point-slope form is y - 1 = -3/2(x - 0).

What of the following statements describes a zero slope? Check all that apply.
The line goes up when moving right to left.
The line goes down when moving right to left.
The line is horizontal.
The line is vertical.
The run is zero.
The rise is zern
Answer:
A,D,E
Step-by-step explanation:
Answer:
A) The line goes up when moving right to left
False. The slope being zero means there is no change in elevation or height. The line is completely flat and horizontal. Recall that slope = rise/run. If the slope is 0, then the rise must be 0.
B) The line goes down when moving right to left.
False. The same reasoning as choice A
C) The line is horizontal
True. Any line with a slope of zero is going to be horizontal. For instance, the equation y = 0x+5 is the horizontal line through 5 on the y axis.
D) The line is vertical
False. This contradicts choice C above. Vertical lines have undefined slopes which aren't numbers due to the fact we cannot divide by zero.
E) The run is zero
False. The run can be any number but zero. For example, slope = 0 = 0/1 or 0 = 0/5. Dividing zero over any nonzero number leads to 0.
F) The rise is zero
True. As mentioned before in previous answer choices (see choice A in particular).
===========================================
In summary, there are only two true statements and they are choice C and choice F. The other statements are false.

Given the speeds of each runner below, determine who runs the fastest. \text{Brooke runs 13 feet per second.} Brooke runs 13 feet per second. \text{Will runs 308 feet in 26 seconds.} Will runs 308 feet in 26 seconds. \text{Ron runs 1 mile in 551 seconds.} Ron runs 1 mile in 551 seconds. \text{Debbie runs 658 feet in 1 minute.} Debbie runs 658 feet in 1 minute.
Answer:
Brooke runs the fastest.
Step-by-step explanation:
Brooke runs 13 feet per second.
Therefore, speed of Broke = 13 feet per sec.
Will runs 308 feet in 26 seconds.
Speed of Will = [tex]\frac{\text{Distance}}{\text{Time taken}}[/tex]
= [tex]\frac{308}{26}[/tex]
= 11.85 feet per second
Ron runs 1 mile in 551 seconds.
1 mile = 5280 feet
Speed of Ron = [tex]\frac{5280}{551}[/tex]
= 9.58 feet per second
Debbie runs 658 feet in 1 minute.
1 minute = 60 seconds
Speed of Debbie = [tex]\frac{658}{60}[/tex]
= 10.97 feet per seconds
Here, speed of Brooke is the maximum.
Therefore, Brooke runs the fastest.

Dillon deposited 3/4 of his paycheck into the bank. If he deposited $46.50 into his bank account, what was the amount of the paycheck?
Answer:
$62
Step-by-step explanation:
Take $46.50 and divide it by 3 to get 1/4 of the paycheck
46.50/3 = 15.50
Then multiply 15.50 by 4 to get the whole pay check

Step-by-step explanation:
the shape is a tryangle so it will have the same angle measurements, just make sure you look if it has the slash next to the letter or not in the future
Hope this helps girly!!
Answer:
[tex]\angle{C}=54[/tex]
Step-by-step explanation:
Let's first start by establishing that when it comes to a reflection, side lengths and angle measurements remain the same. With that being said, let's identify our angle measurements:
[tex]\angle{A=}\\\angle{B}= 67\\\angle{C}=\\\angle{A'}=59\\\angle{B'}=\\\angle{C'}=\\[/tex]
As mentioned earlier, angle measurements will remain the same, so we can go ahead and identify the values of [tex]\angle{A}[/tex] & [tex]\angle{B'}[/tex]
[tex]\angle{A=59}\\\angle{B}= 67\\\angle{C}=\\\angle{A'}=59\\\angle{B'}=67\\\angle{C'}=\\[/tex]
The sum of the angles in a triangle will always be equal to 180°.
Add the two identified angles of the original figure.
[tex]59+67=126[/tex]
Subtract the sum from 180:
[tex]180-126=54[/tex]
Therefore:
[tex]\angle{C}=54[/tex]
_
Check your work by adding the three identified angle measurements to see if they measure to 180°:
[tex]59+67+54[/tex]
[tex]=180[/tex]

What is the unit rate?
y=5x
Answer:
In the equation y=5x the slope (m) is 5, and the y-intercept is the point (0,0) since there is nothing added or subtracted to the 5x, and thus b = 0.
Step-by-step explanation:
Answer:
measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour,
A culture of bacteria has an initial population of 41000 bacteria and doubles every 5 hours. Using the formula P t = P 0 ⋅ 2 t d P t =P 0 ⋅2 d t , where P t P t is the population after t hours, P 0 P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 14 hours, to the nearest whole number?
Answer:
Population of bacteria in culture after 14 hours is 285541.
Step-by-step explanation:
We are given with [tex]P_{t} =P_{0}(2)^{\frac{d}{t}}[/tex]
Here initial population is 41000 , t=5 and d=14
Plug in these values into the formula
[tex]P_{14} =41000(2)^{\frac{14}{5} }[/tex]
Simplify
[tex]P_{14}= 41000(2)^{2.8}[/tex]
=41000(6.9644)
=285540.5847...
To the nearest whole number is 285541.
Answer:
285541.
Step-by-step explanation:
P0=41000-The initial population
t=14-Time elapsed
d=5-The doubling time
Pt=P0⋅2^t/d
Pt=41000⋅2^14/5-Plug in
Pt=285540.5848≈285541-(Use parenthesis in the calculator for the exponent)

Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each. How many rides will Luka need to ride in order to spend $20?
Answer:
He would have to do 13 rides.
Step-by-step explanation:
If he initially pays $7, which lets him pay only $1 for each ride, so when he spends $20, he would have done 13 rides.
There are 13 rides will Luka need to ride in order to spend $20.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each.
Here, Luka need to ride in order to spend $20.
Let number of rides = x
So, We can formulate;
⇒ $7 + $1x = $20
⇒ 7 + x = 20
Solve for x as;
⇒ x = 20 - 7
⇒ x = 13
