Question #N191
A line passes through the points $(2, 3)$ and $(6, -1)$. What is the slope of this line?
A. -1
B. -2
C. 1
D. 2
Correct Answer is: A
The slope of a line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula \frac{y_2 - y_1}{x_2 - x_1}. Plugging in the given points, we get \frac{-1 - 3}{6 - 2} = \frac{-4}{4} = -1.
