Answer
$m = 0$
Work Step by Step
We are given the two points $(-4, 2)$ and $(5, 2)$.
Let's use the formula to find the slope $m$ given two points:
$m = \frac{y_2 - y_1}{x_2 - x_1}$
Let's plug in the values into this formula:
$m = \frac{2 - 2}{5 - (-4))}$
Subtract the numerator and denominator to simplify:
$m = \frac{0}{9}$
Any fraction with $0$ as its numerator equals $0$:
$m = 0$
