# How do you find the slope for (-3,-3); (0,0)?

May 14, 2015

The slope, $m$, of the line that passes through points $\left(- 3 , - 3\right)$ and $\left(0 , 0\right)$ is $1$.

The formula for finding the slope, $m$, of a line from two points on the line is:

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

Point 1 = $\left(- 3 , - 3\right)$
x_1=-3 y_1=-3

Point 2 = $\left(0 , 0\right)$
${x}_{2} = 0$
${y}_{2} = 0$

Solve for slope.

$m = \frac{0 - \left(- 3\right)}{0 - \left(- 3\right)} = \frac{\cancel{3}}{\cancel{3}} = 1$ =

$m = 1$
