Question #N127
A line passes through the points $(1, -2)$ and $(4, 4)$. What is the slope of the line?
A. -2
B. -1
C. 2
D. 3
Correct Answer is: C
The slope of a line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula: $\frac{y_2 - y_1}{x_2 - x_1}$. Substituting the given points, we get: $\frac{4 - (-2)}{4 - 1} = \frac{6}{3} = 2$.
