### Example Question #32 : Functions And Graphs

Find the y-intercept of the following equation:

Explanation:

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 #31 : Functions And Graphs

Find the y-intercept of the following equation:

Explanation:

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 #34 : Functions And Graphs

Find the y-intercept of the following equation:

Explanation:

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
