Question #N318
A line passes through the points (-1, 2) and (3, -2). What is the slope of the line?
A. -1
B. -2
C. 1
D. 2
Correct Answer is: A
The slope of a line passing through two points can be found using the formula: \begin{align*}m &= \frac{y_2 - y_1}{x_2 - x_1} \\ &= \frac{-2 - 2}{3 - (-1)} \\ &= \frac{-4}{4} \\ &= -1. \end{align*} Therefore, the slope of the line is -1.
