Answer
$m = 2$
Work Step by Step
We are given the two points $(0, -4)$ and $(2, 0)$.
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:
$m = \frac{0 - (-4)}{2 - 0)}$
Subtract the numerator and denominator to simplify:
$m = \frac{4}{2}$
Simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is $2$:
$m = 2$
