Question

Line e has a slope of -2/9. line f is perpendicular to e. what is the slope of f

Answer 1

Answer:

9/2

Step-by-step explanation:

In order to find the slope of a line that is perpendicular to another line, you must find the opposite and reciprocal of that slope. So, you have 2/9, and then 9/2.

Answer 2

Answer:

slope of f = $\frac{9}{2}$

Step-by-step explanation:

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{2}{9} }$ = $\frac{9}{2}$
