Answer:

You would plot the following points, remembering that they’re in the form (x,y) = (time, height):

(1,35) (2,60) (3,92) (4,120) (5,175)

The ordered pairs would be closer together, and there would be 4 times more of them if you were to measure every 15 seconds instead. You would have a line with more points that were closer together.
