Sometimes the quickest and easiest two points to use to graph a line that is not in slope-intercept form are the - and -intercepts. Determine 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.

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.
