Question

Which of the following is an equation of a line perpendicular to the equation y=-2/3x-4

A.Y= - 2/3x+1
B.Y=3/2x+1
C.Y=2/3x+1
D.Y= -3/2x+1

Note: the slashes are meant to as a fraction

Answer 1

B

Explanation:

Perpendicular lines have related slopes. The slopes are negative reciprocals of each other. The slope of y=-2/3-4 is -2/3. So the perpendicular line will have slope 3/2. Y=3/2+1 is the solution.
