Question

What is the slope of a line that is perpendicular to the line 2y – 3x = 8?

Answer 1

`(-2)/(3)`

Explanation:

2y - 3x = 8

2y = 3x + 8

y =
`(3)/(2)` x +4

It is similar to y = mx + b

Therefore m =
`(3)/(2)`

To check whether a line has perpendicular slope we check the product of the slopes to be -1.

The perpendicular slope is
`(-2)/(3)`
