Question #N506
A line passes through the points $(2, 5)$ and $(-1, -4)$. What is the slope of the line?
A. -3
B. -\frac{1}{3}
C. \frac{1}{3}
D. 3
Correct Answer is: D
The slope of a line passing through points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula \frac{y_2 - y_1}{x_2 - x_1}. Substituting the given points, we get \frac{-4 - 5}{-1 - 2} = \frac{-9}{-3} = 3. Therefore, the slope of the line is 3.
