Answer

$m = -1$

Work Step by Step

We are given the two points $(6, -2)$ and $(1, 3)$. Let's use the formula to find the slope $m$ given two points: $m = \frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1, y_1)$ and $(x_2, y_2)$ are points on the line. Let's plug in the values into this formula: $m = \frac{3 - (-2)}{1 - 6}$ Subtract the numerator and denominator to simplify: $m = \frac{5}{-5}$ Divide both the numerator and denominator by their greatest common denominator, $5$: $m = -1$
