Question

Find the constant of proportionality (r) in the equation y = r x

Answer 1

r = 11

Explanation:

y = r x

r is the constant of proportionality

To find r pick any values of x and y provided and substitute it into the above formula and solve for r.

That's

using

x = 2

y = 22

We have

22 = 2r

Divide both sides by 2

r = 11

Therefore the constant of proportionality is 11
