slope = $-\frac{4}{3}$ The line through the points falls from left to right.
RECALL: The slope of the line that passes through the points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula: $m=\dfrac{y_2-y_1}{x_2-x_1}$ Solve for the slope of the line that passes through the two given points using the formula above to obtain: $m=\dfrac{-3-1}{-4-(-7)}=\dfrac{-4}{-4+7}=\dfrac{-4}{3}$ A line with a negative slope falls from left to right.
