use the graph to find the slope.\nslope = \\frac{rise}{run}\nthe runners speed is \\square minutes per mile.

Explanation:

Step1: Identify two points on the line

Let's take the points ((1.0,10)) and ((2.0,20)) from the graph.

Step2: Calculate the rise and run

The formula for slope (m=\frac{\text{rise}}{\text{run}}), where (\text{rise}=y_2 - y_1) and (\text{run}=x_2 - x_1). For the points ((x_1,y_1)=(1.0,10)) and ((x_2,y_2)=(2.0,20)), (\text{rise}=20 - 10=10) and (\text{run}=2.0 - 1.0 = 1.0).

Step3: Find the slope

(m=\frac{10}{1.0}=10)

Answer:

(10)
