Answer:

y = 9x

Step-by-step explanation:

Given

(2,18)

Required

Represent with a proportional equation

A proportional equation is

y = kx

Where k represent the constant of proportionality

And

(x,y) = (2,18)

Substitute values for x and y

y = kx becomes

18 = k * 2

Multiply both sides by ½

½ * 18 = k * 2 * ½

9 = k

k = 9

Recall that the equation is y = kx

Substitute 9 for k

y = 9x
