$m = 2$
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 $2$: $m = 2$
