Question

Numbers are 15,20,25,30 and then there is 3,4,5,6. Whats the constant proportionality and equation?

Answer 1

If two variables are proportional, the ratio of corresponding values will always be constant. Let k represent the constant of proportionality.

Given that the variables are y and x, the equation would be

y = kx

k = y/x

Therefore,

k = 15/3 = 20/4 = 25/5 = 30/6 = 5

The constant of proportionality is 5

The equation is

y = 5x
