Answer:

  use the slope formula

Step-by-step explanation:

Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.

  m = (y2 -y1)/(x2 -x1)

For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...

  (hours, miles) = (1, 25) and (2, 75)

The corresponding slope on that interval is ...

  m = (75 -25)/(2 -1) = 50 . . . . miles per hour

__

You can identify four (4) regions on this graph in which the slope is constant:

  (0, 1) . . . slope is 25 mph

  (1, 2) . . . slope is 50 mph, as computed above

  (2, 3) . . . slope is 0 (the rider has stopped)

  (3, 5) . . . slope is 25 mph

Over different intervals, you need to identify the points involved and use the formula to compute the average slope.
