Question

The tallest escalator on the London Underground system is at Angel Station. It rises to a height of 90 feet over a horizontal distance of 200 feet. Let e(x) be the height of one of the escalator's steps as a function of the horizontal distance from the bottom step.
The following table shows the coordinates of a linear function.

Find and compare the rate of change of e(x) and f(x). Which has the greater rate of change and by how much?
