Question

Tell whether this is a linear relationship, is not one, or it's impossible to tell. A group of cooks spent 3 hours to bake 7 cakes, and 12 hours to bake another 28 cakes.

Answer 1

It is linear.

Explanation:

If you divide 3 hours by 7 cakes, that means they bake 1 cake for every 3/7 of an hour.

If you divide 12 hours by 28 cakes, that also means they bake 1 cake every 3/7 of an hour.
