A scatterplot has a horizontal x-scale from 0 to 16 in increments of 2 and a vertical y-scale from 0 to 10 in increments of 1. Eleven points strictly follow the pattern of a line passing through the points (4, 2) and (14, 7). All coordinates are approximate.

A scatterplot has a horizontal x-scale from 0 to 16 in increments of 2 and a vertical y-scale from 0 to 10 in increments of 1. Eleven points strictly follow the pattern of a curve that rises from left to right passing through the points (4, 3.2) and (7, 7.2) to a peak at (11, 9.2) and then falls to (14, 8.2). All coordinates are approximate.
