Question

Line A and Line B are
perpendicular lines.
If the slope of Line
A is 4/5, what is
the slope of Line B?

Answer 1

Answer:

C

Step-by-step explanation:

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

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{4}{5} }$ = - $\frac{5}{4}$ ← slope of line B

Answer 2

The answer is

-5/4

this is dude to the slip being perpendicular which means that Line B will be the opposite reciprocal to Line A.

Line A=4/5
Line B=-5/4
