What is the slope of the line shown?

Anarel [89]

Hello!

$\large\boxed{Slope = -\frac{1}{2}}$

Use the slope formula along with provided points to solve for the slope.

We can use the points (-4, -1) and (0, -3) and plug these values into the equation:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m = \frac{-3-(-1)}{0-(-4)} \\\\m = \frac{-2}{4} \\\\m = -\frac{1}{2}$
