Plot the points on your graph paper to answer the question. x 0 1 2 3 4 y 0 3 6 9 12 are the paired points in a proportional relationship?

Yes! All the domain (or x numbers) are increasing by 1. All the range (or y numbers) are increasing my 3 each time. If you were to put it on a graph, you would see the line straight and increasing in a congruent proportion.
