Question

review: you use about 1500 calories every day without exercise. if you walk for exercise, you will need additional calories. use the graph to find the rate of calories burned per mile. step 1 label the change in each direction.

Explanation:

Step1: Find change in x (miles)

The two points are (3, 1725) and (9, 2175). Change in x: \( 9 - 3 = 6 \) miles.

Step2: Find change in y (calories)

Change in y: \( 2175 - 1725 = 450 \) calories.

Step3: Calculate rate (calories per mile)

Rate = \( \frac{\text{Change in y}}{\text{Change in x}} = \frac{450}{6} = 75 \) calories per mile.

Answer:

The rate of calories burned per mile is 75.
