Question

What is the slope of a line perpendicular to the line whose equation is 10x + 6у –84. Fully simplify your answer.​

Answer 1

The slope is 3/5.

Explanation:

I am assuming you mean

10x + 6y = 84

6y = -10x + 84

y = -5/3 x + 14.

So the slope of this line is -5/3 and the slope of a line perpendicular to it is

-1 / -5/3 = 3/5.
