(-2,-1) and (0,1) slope intercept
(stuck on it)
Slope intercept form of (-2,-1) and (0,1) is y = 3/2x +1.
Define slope intercept form.The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation. The slope, m, is a measure of how steep a line is. Simply put, the slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This form is frequently known as the y = mx + b form.
Given,
Coordinates = (-2,-1) and (0,1)
For slope:
m = y₂ - y₁/ x₂ - x₁
m = 1 + 2/0 + 2
m = 3/2
Slope intercept form:
y = mx + b
y = 3/2x +1

Marie will earn $15 Per hour at a new job. During training, she will earn $10 per hour.
What percent of Marie's regular hourly rate will she earn during training
The percent that Marie will earn during her training is 66.67%.
What is percentage?
Percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Given,
She earns working in new job = $15
She earns while training = $10
percentage she will earn during her training
= earing during training/earning during job multiplied by 100.

What is the change to the graph of y=−3x−2 when the slope is changed to −1/3?
The slope of the graph will be changed. The graph is still a straight line, But it becomes steep.
The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.
Slope of a Line :
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.
where "m" represents a line's slope.

Step-by-step explanation:
a political candidate has asked you to conduct a poll to determine what percentage of people support her. if the candidate only wants a 2% margin of error at a 90% confidence level, what size of sample is needed?
Size of sample needed to determine the percentage of people with give margin of error is equal to 1691.
As given in the question,
Margin of error = 2%
= 0.02
Sample proportion 'p' = 0.5
⇒ (1 - p) = 1 - 0.5
= 0.5
Let 'n' represents the sample size
Z- value at confidence interval 90% = 1.645
Formula used
Margin of error = z-value √ [p( 1-p)/n]
Substitute the value we get,
0.02 = 1.645 √ (0.5)(0.5)/n
Squaring on both the side
0.0004 = 2.706025 ( 0.25/n)
⇒ n = ( 2.706025 × 0.25 )/ 0.0004

The perimeter (adding up all the sides) of a rectangular piece of land is 228 feet. The length of the land is 74 feet and its width is 154 feet.
Define perimeter.The perimeter of a closed plane figure is referred to in geometry. You might have studied perimeter calculations in school. An equilateral triangle has a 27-foot perimeter if each of its nine sides is the same length. The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeter, meters, inches, and feet.
Given,
Perimeter = 228 feet
Length = x
Width = 2x + 6
Perimeter of rectangle = Length + Width
228 = x + 2x + 6

The amount owed at the end of the 6 years duration is $10865
How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865
Hence, the value of the amount after 6 years is $10865

Hint: Set up an equation to represent the scenario. Here is how you should set your equation up.
A. 3 math questions and 5 science questions
B. 2 math questions and 7 science questions
C.5 math questions and 1 science question
D.4 math questions and 3 science questions
The option she should choose based on the given condition is Option B 2 math questions and 7 science questions.
What are linear inequalities?
When two linear expressions are compared using the inequality symbols, that is an expression of a linear inequality.
Given, Time is taken for solving single math question = 12 minutes
Time is taken for solving single science question = 5 minutes
Let 'x' be the total number of math questions and 'y' be the total number of science questions.
Then,
The total time taken for 'x' math questions = 12x minutes
The total time taken for 'y' science questions = 5y minutes
So, as defined in the question, we get
Total time she wants to spend practicing < 60 minutes
i. e. 12x + 5y < 60 .................... (i)
Now, we check this condition for each answer choice
A) x = 3 and y = 5, substituting values in equation (i)
So, 12*3 + 5*5 < 60
or, 36+25 < 60
or, 61 < 60 (Not valid)
B) x = 2 and y = 7, substituting values in equation (i)
So, 12*2 + 5*7 < 60
or, 24+35 < 60
or, 59 < 60 (Valid)
So, Option B is valid.
Hence, the required answer of choice is Option B i.e. 2 math questions and 7 science questions.

Given, a system of equations
x + 5y - 3z = 19
2x - 3y + 4z = -11
4x + y - 2z = 0
On multiplying eq (1) by 2, we get
2x + 10y - 6z = 38
On subtracting eq (1) and (2), we get
13y - 10z = 49 ... (4)
Now, On multiplying eq (2) by 2, we get
4x - 6y + 8z = -22
On subtracting eq (3) and (2), we get
7y - 10z = 22 ... (5)
Now, on subtracting eq (4) and (5), we get
6y = 27
y = 9/2
On substituting the value of y in Eq (5), we get
z = 19/20
Now, On substituting the value of y & z in Eq (1), we get
x + 5(9/2) - 3(19/20) = 19
x + 45/2 - 57/20 = 19
x + 393/20 = 19
x = -13/20
