Question

A line of the equation has a slope of a/b, where a and b are integers.

What is the slope of the line that is perpendicular to this line?

Answer 1

Answer:

-b/a

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals. That means that their product is -1.

slope of line = a/b

slope of perpendicular = -b/a
