Question

Four graphs are shown. All the graphs show scale on x axis and y axis from 0 to 10 at increments of 1. Graph A shows dots at ordered pairs 0, 2 and 1, 3 and 3, 5 and 4, 6 and 5, 7 and 6, 8 and 7, 9 and 8, 10. Graph B shows dots at ordered pairs 0, 10 and 1, 9 and 2, 8 and 3, 7 and 4, 6 and 5, 5 and 6, 4 and 7, 3 and 8, 2 and 9, 1. Graph C shows dots at ordered pairs 0, 10 and 0, 9 and 0.9, 8 and 1.1, 7 and 1.5, 6 and 2, 5.5 and 2.1, 4 and 2.5, 4.9 and 3, 4.1 and 3, 5.1 and 3.8, 3.5 and 3.9, 4.5 and 4.2, 3 and 5, 2.8 and 5, 3.8 and 6, 2.4 and 6, 3.1 and 6.8, 2.9 and 7, 2.1 and 8, 2 and 8, 2.8 and 9, 2 and 10, 2. Graph D shows dots at the ordered pairs 0, 0.5 and 1, 0.5 and 2, 0.6 and 3, 0.8 and 3.1, 1.5 and 4, 0.9 and 4, 1.8 and 5, 1.1 and 5.1, 2.1 and 5.9, 1.9 and 6.1, 3 and 6.8, 2 and 7, 4 and 7.1, 3 and 7.6, 5 and 8, 3.8 and 8, 4.4 and 8.1, 6 and 8.5, 7 and 8.6, 5 and 8.8, 6.5 and 9, 8 and 9, 9 and 9, 10.
Which graph represents a positive nonlinear association between x and y? (1 point)

Graph A
Graph B
Graph C
Graph D

Answer 1

Graph C represents a positive nonlinear association between x and y, as the points on this graph are not falling on a straight line, but rather curving upward.
