Use the graph to find the slope. slope = the runner’s speed is minutes per mile.

Solution:

Given, slope = the runner’s speed in minutes per mile.

We have to find the slope using the given graph.

Slope = rise/run

First find the amount the graph rises (up or down) between two points.

Second, find the amount (left to right) between the same two points.

From the graph,

1) rise = 5

run = 0.5

Slope = 5/0.5 = 10

2) rise = 10

run = 1

Slope = 10/1 = 10

3) rise = 15

run = 1.5

Slope = 15/1.5 = 10

4) rise = 20

run = 2

Slope = 20/2 = 10

5) rise = 25

run = 2.5

Slope = 25/2.5 = 10

Therefore, the slope is 10 minutes per hour.

Use the graph to find the slope. slope = the runner’s speed is minutes per mile.

Summary:

Using the graph, the slope is 10 minutes per hour.
