How to find the slope of a perpendicular line Practice Test

A line in the x-y plane passes through the points (3,5) and (–2, 4). Another line does not pass through the origin, and does not have the same intercept as the first line. If the two lines are perpendicular, what is the slope of the second line?

What is the slope of a line perpendicular to line passing through the points (5, 7) and (2, 12)?
