Question

What is the slope of a line perpendicular to the line whose equation is -2x+20y=6​

Answer 1

-10

Explanation:

Solving for y gives ...

20y = 2x +6

y = 2/20x +6/20 = 1/10x +3/10

The slope of the given line is the coefficient of x: 1/10. The slope of the perpendicular line is the opposite reciprocal of this: -1/(1/10) = -10.

The perpendicular line has a slope of -10.
