Question

What is the slope of a line perpendicular to the line whose equation is 2x+10y=20. Fully reduce your answer.

Answer 1

Answer:

m=5

Step-by-step explanation:

2x+10y=20

10y=-2x+20

y=-1/5x+2

slope of this line=-1/5

(replace the denominator by the nominator and the nominator by the denominator and change the sign to the opposite one negative to positive)

slope of perpendicular line=5
