Question

What is the slope of a line that is perpendicular to the line
that passes through the points (4,7) and (9,3)?

Answer 1

Answer:

$\frac{5}{-4}$

Step-by-step explanation:

Slope = y2-y1/x2-x1

(4,7) = (x1,y1)

(9,3) = (x2,y2)

Slope = (3-7)/(9-4)

          = -4/5

The perpendicular slope is reciprocal so it would be 5/-4
