Question

20 points!!!!

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:

Product of slope of perpendicular line = -1

Slope =
`(y_(2)-y_(1))/(x_(2)-x_(1))\\`

`= (7-0)/(3-9)\\\\=(7)/(-6)\\\\=(-7)/(6)`

Slope of the perpendicular line = -1/m = -1 ÷
`(-7)/(6)`

`= -1 * (-6)/(7) = (6)/(7)`
