Choose the correct graph below. A. 0 10 0 20 x y A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 2. The following 5 points are plotted, listed here from left to right: (2, 18); (4, 14); (7, 11); (7, 8); (8, 4).
