Y is directly proportional to X. when x=500, y=10, find the formula for y in terms of x?

y=kx, where k is the constant of proportionality. So plug in 10 for y. Plug in 500 for x and solve for k.

y=kx

10=k*(500)

Divide each side by 500 to isolate the k constant

10/500=k

Simplify

k=1/50 or k=0.02

y in terms of x:

y=(1/50)*x or y=0.02*x

Hope that helps!

10 X 500

y=10,x=500 so y=1/50X

I am assuming you are on graph paper.

x=5, y=.1

x=25, y=.5

x=50, y=1

plot these points...happy graphing

if not your answer is this

y=x/50 or x=y(50)

10 = c * 500

c = 10 / 500 (=0.02)

Your answer is:

y = 0.02 * x
