The slope of the line containing (8,-3) and (-6,-2) is (1/14).
The slope of a straight line can be written as follows,
m = [tex](y_{2} - y_{1} )/(x_{2} - x_{1} )[/tex] equation1
The line is containing the points (-3,3) and (4,3). So, we can write
[tex]y_{2}[/tex] = -2 , [tex]y_{1}[/tex] = -3 , [tex]x_{2}[/tex] = -6 , and [tex]x_{1}[/tex] = 8 .
On substituting the values of variables in equation1, we will get
m = ( (-2)-(-3) ) / ( (-6)-(8) ) = (1/14).
As the slope of a line is (1/14), so we can conclude that the given line is a straight line.
Here:
m = the slope of the line
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] ) are the first coordinates.
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )are the second coordinates.

Write an equation of each line.slope =0 ; through (4,-2)
The equation of the line, with slope equal to 0 and passing through the point located at (4 , -2), is y = -2.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the point slope form, plug in the values to set up the equation.
(y - y1) = m(x - x1)
where m = 0 and (x1 , y1) = (4 , -2)
(y - -2) = 0(x - 4)
(y + 2) = 0
y = -2
In slope-intercept form, the equation of the line is:
(y + 2) = 0
y = -2
In standard form, the equation of the line is:
y = -2

Solving System of Linear Equations GraphicallyFrom the question, we are to determine the number of apples, x, and the number of peaches, y, that Chee bought
From the given information,
She bought $6 worth of apples and peaches
and
Each apple costs $1 and each peach costs $0.50
Then, we can write that
$1 × x + $0.50 × y = $6
x + 0.50y = 6
Also,
She bought 4 times as many peaches as apples
That is,
y = 4x
Now, we will solve the system of equations graphically
x + 0.50y = 6
y = 4x
From the graph, the solution to the system of equations is x = 2, y = 8.

The lowest possible integer value of x is 3 such that (x ≥ 3).
What is referred as the inequalities?An inequality depicts the relationship between two non-equal values in such an algebraic expression. Inequality symbols can indicate that one of the two variables is greater than, greater or equal to, equal to some other value.For the given question;
The area of rectangle A is bigger than the area of rectangle B.
The sides of the rectangle A are 2x-3 and 5 cm.
Area = length×breadth
Area A = (2x - 3)(5)
Area A = 10x - 15
The sides of the rectangle B are x = 2 and 3 cm.
Area = length×breadth
Area B = (x + 2)3
Area B = 3x + 6
As area B > area B
Then,
10x - 15 ≥ 3x + 6
Solving the inequality;
10x - 3x ≥ 6 + 15
7x ≥ 21

Zeros of the function
Intervals where the function is positive and intervals where it is negative
The positive interval is (0,2) and the negative range is calculated as (-4,0) and (2,4).
A graph is used to show the relationship between variables on a coordinate plane.
The domain of the function is [-4,4].
The zeros are: -2,0 and 2.
The positive interval is between (0,2).
The range of negative values is (-4,0) to (2,4). This is the set of x values in the graph. The graph demonstrates that the x value is between -4 and 4.
Thus, the domain is [-4,4]. The zeros of the function: Where it crosses the x- axis. The graph touches the x-axis when it is at -2,0 and 2. As a result, the function has the following zeros:-2,0 and 2.
Positive interval:
On the graph, positive values range from x = 0 to x = 2.
Consequently, the positive interval is (0,2).
Negative duration:
This is the x values when the function gives a negative result.
The graph shows negative values from x = -4 to x = 0, then from x = 2 to x = 4.
The negative range is therefore (-4,0) and (2,4).
Hence, the positive interval is (0,2) and the negative range is (-4,0) and (2,4).

8x - 3y = -1
Answer: If you're solving for the substitution method then your answer would be (1,3)
Step-by-step explanation:
Answer:
x = -4/5
y = 9/5
Step-by-step explanation:
-3y + 2x = -7
8x - 3y = -1
make one of the equations y=....
-3y + 2x = -7
-3y = -7 - 2x
y = (-7 - 2x)/3
now put (-7 - 2x)/3 where y is in the other equation
8x - 3y = -1
8x - 3((-7 - 2x)/3) = -1
8x - 1*(-7 - 2x) = -1
8x + 7 + 2x = -1
solve for x
8x + 7 + 2x = -1
8x+2x = -8
10x = -8
x = -8/10
x = -4/5
now put -8/10 in one of the equations to get what y is
-3y + 2x = -7
-3y + 2(-8/10) = -7
-3y - 16/10 = -7
-3y = -7 + 16/10
-3y = -70/10 + 16/10
-3y = -54/10
y = -54/10 * -1/3
y = 18/10
y = 9/5

The form for slope intercept form is: y = mx + b
Where:
y = y coordinatem = slopex = x coordinateb = y interceptThe y-intercept is the constant. It represents the point where the slope touches the y-axis.

a +2b = 750 equation 1
a + 4b = 870 equation 2
Where:
a = gift
b = amount earned weekly while working on the golf course
Subtract equation 2 from equation 1: 2b = 120
Divide both sides of the equation by 4: b = $60
Substitute for b in equation 1
a + 2(60) = 750
a + 120 = 750
a = 750 - 120

The constant percent rate of change in the case of a deposit of $400 into a savings account is compounded annually.
With an example, what is compound interest?
When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits. Consider that you have $1,000 in a savings account earning 5% interest annually. If you made $50 in the first year, your new balance would be $1,050.Principal - $400
rate of interest is compounded annually
g(x) = 400( 1.03)ˣ equation 1.
Formula used
A = P( 1 + r )ⁿ
here n = x
Solution:
Putting the value of n, and principal in the formula
A = P( 1 + r )ⁿ ................... equation 2
now comparing both equation 1 and equation 2,
400( 1.05)ˣ = 400( 1 + r )ˣ
( 1.05)ˣ = ( 1 + r )ˣ
1.05 = 1 + r
r = 1.05 - 1
r = 0.05
r % = 0.05 × 100
r % = 5 %
