Work Step by Step
We know that this is a linear function because we only have a slope and y-intercept. The y-intercept is interpreted as 0 and the slope is -3. We can simply plug values into x to get our points:
$y=-3(−3)=9$
$y=-3(−2)=6$
$y=-3(-1)=3$
$y=-3(0)=0$
$y=-3(1)=−3$
$y=-3(2)=−6$
$y=-3(3)=−9$
Graph and then connect these points.
