Question

A B C OR D SOMEONE HELP

Answer 1

B

Explanation:

Perpendicular lines have slopes that are negative reciprocals. For example. if the slope of a line is 2, the slope of a line perpendicular to it would be
`-(1)/(2)`. If the slope of a line
`-(1)/(3)`, the slope of a line perpendicular to it would be 3.

Negative reciprocals always have a product of -1, since the numerators cancel out and one of the values is negative.

I hope this helps!
