Question

Line k is perpendicular to the line that passes through the points (5,6) and (6,10). What is the slope of line
k?

Answer 1

Answer: -1/4

Step-by-step explanation:

The slope of the line whose points are given is $\frac{10-6}{6-5}=4$

Perpendicular lines have the same slope, so the slope of line k is -1/4.
