The slope of a line that is perpendicular to a line whose slope is 3/8 is

О - 8/3

o 3/8

оо

The answer is-8/3 ...

-8/3

Step-by-step explanation:

We know that lines that are perpendicular have slopes that multiply to - 1

m1 * m2 = - 1

We know one slope is 3/8 and are looking for the perpendicular slope m2

3/8 * m2 = - 1

Multiply each side by 8/3 to find m2

3/8*8/3 * m2 = - 1*8/3

m2 = - 8/3
