the grade of a hill is its steepness represented as a percent. jin tracks his walking speed up different hills. what does the rate of change, or slope, represent? the rate represents a(n) increase decrease in walking speed of 1 mph for each increase of 1/4% 4% in the grade of the hill.

Answer

Explanation:

Step1: Observe the graph trend

As the grade of the hill (x - axis) increases, the walking speed (y - axis) decreases.

Step2: Analyze the rate of change

We can see that for an increase in the grade of the hill, the walking speed goes down. By looking at the general trend of the data - points, for an increase of 4% in the grade of the hill, the walking speed decreases by 1 mph.

Answer:

The rate represents a(n) decrease in walking speed of 1 mph for each increase of 4% in the grade of the hill.
