How to graph $y=-3x-3$?

Izaiah Bean

To locate the intercept using the $y$ axis, substitute $x=0$ into the equation of the line to find:
$y=-3\cdot 0-3=-3$
So the $y$ intercept is at $\left(0,-3\right)$
To locate the intercept using the $x$ axis, substitute $y=0$ into the equation of the line to find:
$0=-3x-3$
Add $3x$ to both sides to get:
$3x=-3$
By dividing both sides, $3$ to get:
$x=-1$
So the $x$ intercept is at $\left(-1,0\right)$
graph{-3x-3 [-10, 10, -5, 5]}
