7-74.

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

The -intercept is the value of when is .

To find the -intercept, substitute for and evaluate.



The -intercept is . Now do the same for the -intercept, but substitute for instead.

Plot the two intercepts and draw the line to connect them.
Label the intercept points.
