How to graph y = - 3 x - 3 ?

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