Step-by-step explanation:
Let
x ----> the number of questions that you answer correctly on this quiz
y ----> the total number of points you score on this quiz
In this problem
The output value or dependent variable is the total number of points you score on this quiz (variable y)
The input value or independent variable is number of questions that you answer correctly on this quiz (variable x)
we have
This linear equation represent a proportional relationship between the variables x and y
where
k=10
K is the constant of proportionality or slope of the linear equation
Answer:
Step-by-step explanation:
The equation to use to find the radius of a circle is 
The equation to use to find the area of a circle is 
First, add 
inches to the diameter of 
inches. You will get 
inches.
Second, you will want to find the radius. Substitute for 
. Solve to get the radius.
The radius is 
inches.
Next, you substitute for 
in the area equation. Solve to get the area.

Answer:
The equation of line shown in the graph is 
Step-by-step explanation:
We need to find equation of the line shown in graph.
The equation of line will be in slope-intercept form 
where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding y-intercept
Looking at the graph, we can find y-intercept when x =0, the value of y is known as y-intercept.
So, when x =0, y=-1
So, y-intercept is -1
Finding Slope
Now, for finding slope, consider 2 points on graph
(0,-1) and (-2,0)
Slope can be found using formula: 
We have 
Putting values and finding slope:
So, slope is 
Equation of line
Now, equation of line having slope and y-intercept b = -1 is
So, equation of line shown in the graph is
