Answer 1

Is there a real question?

I can't seem to find it...

Explanation:

Answer 2

y = (5/7)x - 13

The slope of this line is (5/7)

I a line has a slope m, then a line perpendicular would have a slope -1/m

In this case m= 5/7

So the perpendicular would be: -1/m = -7/5

Answer: -7/5

In decimal numbers: -1.4
