Answer 3

How did you figure out that he burns 10 calories for every minute of studying?

Answer 4

sorry, that was wrong, i think..

Answer 5

Oh wait, it was right.

Answer 6

To find the slope, find 2 points on the graph, (for me it was (100,10) and (400,40)

Answer 7

Right then do the slope formula, I get that. But I don't get the first part.

Answer 8

Chang burns 10 calories per minute that he studies...Some intense studying!

Answer 9

And it's asking how many minutes he studied per calorie burned, not how many calories her burned per minute studied..

Answer 10

I found that, because the point (100,10) shows that after ten minutes of studying, he burnt 100 calories, so I divided 100 by 10

Answer 11

If you reverse it, then its just
Chang burns a calorie every 1/10 of a minute.

Answer 12

Okay, thank you.

Answer 13

No problem!
