Question

use the definition of perpendicular slope on page 1 of your notes to choose the slope perpendicular 3/4

Answer 1

We have to find the slope of a line that is perpendicular to a line with slope 3/4.

Perpendicular lines have slopes that are negative reciprocals. Then, if m1 and m2 are the slopes of two perpendicular lines, we will have:

`m_1=-(1)/(m_2)`

Then, if one of our lines has a slope of 3/4, perpendicular lines will have a slope m as:

`m=(1)/(-((3)/(4)))=-(4)/(3)`

Answer: the slope of a perpendicular line will be -4/3.
