Question

Each of Liam's neighbors pays him the same amount for walking one of their dogs. Last week, he earned $25 for
walking 4 of his neighbors' dogs. Which graph below best represents the linear relationship between x, the number of
dogs Liam walks, and y, the total amount of money he earns for walking them?

Answer 1

Answer:

The options are not shown, but we can craft the graph so you can find the one that matches it.

We know that:

Each neighbor pays the same, let's define this amount as A.

Last week, he walked 4 dogs, then the amount that he collected must be four times A, or:

4*A

And we know that this amount is $25, then:

4*A = $25

A = $25/4 = $6.25

Then we can write the relationship:

y = $6.25*x

where:

y = money that Liam earns.

x = number of dogs Liam walks.

The graph of this line is shown below.
