Question

Determine whether a proportional relationship exists between the two quantities in Exercise 14. Explain your reasoning.

Answer 1

Yes, it is proportional because if you put it on a graph it would start at the origin an have a straight line up from there. Hope this helps!

Answer 2

Yes

Explanation:

If the rate starts at zero and continues by a multiple or is added by the same number each time, it is proportional.

If you look at the first row, it starts off with the relationship at 0.

If you look at the first column, it is being added by 10 so it is a continued rate of +10

If you look at the second column, it is being added by 5 so it is also a continued rate of +5
