Question

If the slope of one line is 13/8 what is the slope of the line that is perpendicular to it ?

Answer 1

`-(8)/(13)`

Explanation:

To find the slope of the line that is perpendicular to a line with a given slope, we simply take the negative reciprocal of the given slope.

The given slope is:
`(13)/(8)`

The reciprocal is obtained by swapping the numerator and the denominator.

The negative reciprocal of the slope is:
`-(8)/(13)`
