How do you graph y=-3x-3 using slope intercept form?

Feb 21, 2017

The slope obviously is $- 3$ as it's the coefficient of $x$.

Explanation:

The $y$-intercept is when $x = 0$:
$y = - 3 \cdot 0 - 3 = - 3 \to \left(0 , - 3\right)$

The $x$-intercept is when $y = 0$
$0 = - 3 x - 3 \to 3 x = - 3 \to x = - 1 \to \left(- 1 , 0\right)$
