Find the x and y intercepts and draw a line through them.

Explanation:

If you have the equation of a line in standard form ax+by =cax+by=c, then
you can find the x and yxandy-intercepts really easily.

To find the xx-intercept, make color(red)(y=0)y=0

x-color(red)(y) =8xy=8
x-color(red)(0) =8" "larrx0=8 solve for xx
x=8" "larrx=8 this is the xx-intercept

To find the yy-intercept, make color(blue)(x=0)x=0

color(blue)(x) -y =8xy=8

color(blue)(0) -y =8" "larr0y=8 solve for yy
-y=8y=8

y = -8" "larry=8 this is the yy-intercept
graph{x-y=8 [-16.79, 23.21, -16.56, 3.44]}
