Answer:

slope = .4

She ran .4 laps per min.

She ran 12 laps in 30 minutes

Step-by-step explanation:

The slope is the rate of change.  It can be found by using the formula

slope = (y2-y1)/(x2-x1)

 The given points are (11, 4.4)  (5.5 ,2.2)

slope = (2.2-4.4(/ (5.5-11)

           = -2.2/-5.5

          .4

The slope represents .4 laps per min  since y is in laps and x is in minutes.

If she  ran 30 minutes, we multiply the time by the slope to calculate the laps.

30 * .4 = 12

She ran 12 laps.

A) The slope is the change in Y over the change in X.

Using the 2 points given on the graph (11,4.4) and (5.5, 2.2)

The first number in the parenthesis are the X value and the 2nd numbers are the Y values.

Slope = (4.4 - 2.2) / (11-5.5)

= 2.2 / 5.5

= 0.4


B) From the slope, she ran 0.4 laps per minute.


C) To find the total laps, multiple laps per minute by total minutes:

30 minutes x 0.4 laps per minute = 12 laps.
