1/7 what is the slope of the red line?
A.7
B.1/7
C.-7
D. -1/7

Answer 1

c: -7

the slope of a perpendicular line is the negative reciprocal of the original line

a way to find this is to flip the numerator and the denominator of a slope and make it negative

1/7 --> 7 --> -7

that would be your slope
