Question

Thomas has a train collection. He was given 1 train as a gift, and he adds 2 trains per year. Which of the graphs below represents Thomas's

train collection?

Answer 1

I am pretty sure the answer would be Option B.

Explanation:

If you look on the graph, Option B is the one that makes the most sense because it goes up by a ratio of 1:2 just like in the problem, 1 gift train + 2 trains per year.

Option A would not make sense because it goes up by the ratio of 1:3 and doesn't match up with the problem.

Note:

I hope this helps! :) Please correct me if I am wrong.

Answer 2

Graph A

Explanation:

The line starts at 1 since that is what he began with. Then it grows by two because every year he gets too more.
