Question

What is the slope of a line perpendicular to the line whose equation is4x−10y=20. Fully reduce your answer.

Answer 1

Answer:

Step-by-step explanation:

4×-20=10y

4x/10-20/10=y

x/5 -2=y

x/5 +(-2)=y--------(1)

we have

y=mx+c----------(2)

comparing eq. 1 and 2,we get,

slope (m)=1/5

c= -2
