Answer
C
Work Step by Step
We first find the slope of line p. The equation for slope is: $ \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$. Thus, we find:
$\frac{7-(-4)}{2-5}=\frac{-11}{3}$
Recall, slopes of perpendicular lines are the opposite reciprocal of the slope of the original line, so we know that the slope of the perpendicular line is 3/11.
