Question

The graph below shows the distance Sean rode his bike. Does this represent a proportional relationship?

A: No because 1/10 does not equal 10/1


B: No, because there needs to be more info


C: Yes, because he started at 0 and increased by 10 miles each hour


D: Yes, because he rode 1 mile each hour

Answer 1

We can see that for every 1 hour he increases 10 miles in his distance, so we can say it's constant, he started at 0 and increased 10 miles per hour.

Alternative C.

Answer 2

Explanation:

First the line is a straight line. It starts at zero and increases 10 miles every hour. You cannot find a better example of y = kx

I don't know what A means, but it is not the answer. It does not represent what is in the graph.

The information from the graph is just fine. B is not the answer.

D is incorrect. The graph says he rode 10 miles in each hour.

The answer is C. For every hour on his bike, he rides 10 miles. That is a proportional relationship, especially when he starts at 0.
