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

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

Answer 2

C

Explanation:

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

`m_(perpendicular)` = -
`(1)/(m)` = -
`(1)/((4)/(5) )` = -
`(5)/(4)` ← slope of line B
