Question

The slope of a line that is perpendicular to a line whose slope is -2/7 is

a) -2/7
b) -7/2
c) 7/2

Answer 1

You just need to flip the sign and the numbers.

-2/7= 2/7

7/2

So, "C" is the correct answer.

I hope this helps!

Answer 2

The answer is C.

Perpendicular lines have opposite reciprocal slopes. That means one is negative and the other is positive, and the fractions are flipped.
