Example Questions
Example Question #16 : X Intercept And Y Intercept
Find the y-intercept of the following equation:
In order to find the y-intercept, set x=0 then solve for y. For this equation that looks as follows:
Divide both sides by 2 to get y by itself:
This gives a final answer of y=3/2
Example Question #21 : X Intercept And Y Intercept
Find the y-intercept of the following equation:
In order to find the y-intercept, set x=0 then solve for y. For this equation that looks as follows:
Divide both sides by -1 to get y by itself:
This gives a final answer of y=-12
Example Question #22 : X Intercept And Y Intercept
Find the y-intercept of the following equation:
In order to find the y-intercept, set x=0 then solve for y. For this equation that looks as follows:
This gives a final answer of y=2
Example Question #23 : X Intercept And Y Intercept
What is the y-intercept of the following equation?
Rewrite the equation in slope-intercept form:
Our objective is to determine the value of 
Add two on both sides.
Divide by 2 on both sides.
The value of 
Example Question #24 : X Intercept And Y Intercept
What is the y-intercept of the following?
The y-intercept is the value of 
Substitute the value of 
The answer is:
Example Question #23 : X Intercept And Y Intercept
What is the x-intercept of the equation 
The x-intercept is the value of x when 
Add two on both sides, and then divide both sides by three.
The answer is:
Example Question #26 : X Intercept And Y Intercept
Define 
Give the 
The graph of 
The graph of
Evaluate 
A negative number cannot have a logarithm, so 
Example Question #1 : Slope
What is the slopeof the line between the points (-1,0) and (3,5)?
For this problem we will need to use the slope equation:
In our case 
Therefore, our slope equation would read:
Example Question #2 : Slope
What is the slope of the function
4
6
2
3
2
To find the slope of this function we first need to get it into slope-intercept form
To do this we need to divide the function by 3:
From here we can see our m, which is our slope equals 2
Example Question #1 : Slope
What is the slope for the line having the following points: (1, 5), (2, 8), and (3, 11)?
3
5
4
2
3
To find the slope for the line that has these points we will use the slope formula with two of the points.
In our case 
Now we can use the slope formula:
