Question

Which of the following lines is not perpendicular to y = –1.5x + 11?A. y =2/3x + 5B. 3y = 2x – 9C. 2y = 3x + 10D. –2x + 3y = 7

Answer 1

Answers:

B. 3y = 2x – 9

is not perpendicular to the given line.

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals

Given the line

y = -1.5x + 11

The slope is -1.5 or -3/2

Any line perpendicular to the one above must have its slope as 2/3

A. The slope is 2/3 . CORRECT

B. The slope is 2/3. CORRECT

C. The slope is 3/2. WRONG

D. The slope is 2/3. CORRECT
