Question

Find the slope of a line perpendicular to a line through the given points.

E(5, 7), F(3, 1)

Answer 1

m=-1/3

Explanation:

Since we are finding the perpendicular slope, we use the negative reciprocal of the original slope.

m=y2-y1/x2-x1

m=1-7/3-5

m=-6/-2

m=3

The negative reciprocal of 3 is -1/3. Therefore, -1/3 is our perpendicular slope.

Answer 2

the slope of a line going through points (5,7) and (3,1) is 6/2 so 3/1 = slope of 3
