$$m = 3$$ Because the slope is positive, the line rises from left to right.

Work Step by Step

To find the slope, we use the formula: $$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$$ We now plug in the given points into this equation to find the slope of this line: $$m = \frac{-4 - 2}{-3 - (-1)}$$ Simplify: $$m = \frac{-6}{-2}$$ $$m = \frac{6}{2}$$ Simplify the fraction: $$m = 3$$ Because the slope is positive, the line falls from left to right.
