What is the meaning of the slope of the line in this context?

The correct answer is D) The rate in which he burns calories

Step-by-step explanation:

We can tell this because the slope is always the change in y value over the change in x value. Since the y value is calories and the x value is minutes, we get the following.

Calories/minute

Which can also be written as calories per minute, which is a rate.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
