Which line has an y-intercept of -2

The y-intercept is found when x is set to 0.

Set x to equal 0 for both equations:




Divide both sides by -2:



The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.

-



Divide both sides by 2:



The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.

Neither line has a y-intercept of -2.
