Answer:
6/7
Step-by-step 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
