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 , which represents the y-intercept.
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 when .
Substitute the value of into the given equation.
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 -coordinate of the -intercept of the graph of (nearest hundredth).
The graph of has no -intercept.
The graph of has no -intercept.
Evaluate :
A negative number cannot have a logarithm, so is an undefined expression. Therefore, the graph of has no -intercept.
