Question

Line c passes through points (1, 14) and (7, 7). Line d is perpendicular to c. What is the slope of line d?

Answer 1

Answer:

6/7

Step-by-step explanation:

Your first step will be to find the slope of Line C. Using the slope formula of $\frac{y_{2}-y_1 }{x_2-x_1}$, the slope of Line C is $\frac{7-14}{7-1} = \frac{-7}{6}$.

If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.
