Question

The coordinates of point E are (−9, −5) and the coordinates of point F are (−2, −1) .

What is the slope of the line that is perpendicular to EF¯¯¯¯¯?

Enter your answer as a simplified fraction in the box.

Answer 1

first step: use the slope formula to calculate the slope between E and F

Answer 2

ok

Answer 3

so answer is
4/7?

Answer 4

for the slope

Answer 5

second step: since we want the "perpendicular" slope we take 4/7, flip the numerator and denominator, then multiply by -1

Answer 6

so your answer = -7/4

Answer 7

ohh i see thnx again !!
