Question

The variables x and y have a proportional relationship, and y= 5/6 which equation represents this relationship? x= 3/4. Which equation represents this relationship?

Answer 1

(d) y= (1 1/9)x

Explanation:

A proportional relation is described by the equation ...

y = kx

Dividing by x shows how to find the value of k:

k = y/x

For the given values of y and x, the value of k is found to be ...

k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9

The relationship is represented by the equation ...

y = (1 1/9)
