2-71.

Sometimes the quickest and easiest two points to use to graph a line that is not in slope-intercept form are the *x-* and *y-*intercepts. Determine the *x-* and *y-*intercepts for the two lines below and then use them to graph each line. Write the coordinates of the *x-* and *y-*intercepts on your graph. Homework Help ✎

The

*y*-intercept is the value of*y*when*x*is 0.To find the

*y*-intercept, substitute 0 for*x*and evaluate.

0 − 2*y*= 4

−*2*y = 4

*y*= −2

The*y*-intercept is (0, −2). Now do the same for the*x*-intercept, but substitute 0 for*y*instead.Plot the two intercepts and draw the line to connect them.

Label the intercept points.
