Question

The lines below are perpendicular. If the slope of the green lines in 3/2, what is the slope of the red line

Answer 1

Answer:

-2/3

Step-by-step explanation:

Where 2 lines are perpendicular,  the slope of one = - 1 / slope of the other.

Thus the slope of the red line  is - 1 / 3/2

= -2/3

Answer 2

Answer:

slope of red line = - $\frac{2}{3}$

Step-by-step explanation:

the product of the slopes of perpendicular lines = - 1

given m = $\frac{3}{2}$ then

$m_{red line}$ = - $\frac{2}{3}$ ← product of slopes = - 1
