2-70.

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. Find 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.

1. $x−2y=4$

1. $3x+6y=24$

The $y$-intercept is the value of $y$ when $x$ is $0$.

To find the $y$-intercept, substitute $0$ for $x$ and evaluate.
$0−2y=4$
$−2y=4$
$y=−2$
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.
