Question

What is the slope of a line that is perpendicular to the line that passes through the points (9,0) and (3,7)?

Answer 1

6/7

Explanation:

so, here's the thing ,the product of the slopes of perpendicular lines when multiplied must be equal to -1. So in this situation ,first find the slope of the line that passes through the given points like this :

m = y2 - y1 / x2- x1 (formula for the slope)

m= 7 - 0 / 3- 9

m=7 /-6

now you can find the perpendicular slope like this

m1 * m2= -1. (m1 = 7/-6)

7/-6 *m2=-1

m2 = 6/7
