Answer
slope = 4
The line through the points rises from left to right.
Work Step by Step
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:
$m=\dfrac{8-4}{3-2}=\dfrac{4}{1}=4$
A line with a positive slope rises from left to right.
