Thegraph shows the relationship between thenumber of bottles of paint, x, she buysand the ounces of paint, y, that she has.Bottles of Paint20Paint (ounces?105041 2 3Number of BottlesWhat is an equation in terms of x and ythat can be used to model theproportional relationship?

Answer 1

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form

y=kx

where k is the constant of proportionality or slope

In this problem we have a proportional relationship

step 1

Find the value of k

we need one point

i take the point (1,5)

k=y/x

k=5/1=5

the linear equation is

y=5x
