The graph shows the heights, y (in centimeters), of a plant after a certain number of weeks, x. Donna drew the line of best fit on the graph. A graph titled Plant Height shows Number of Weeks on x axis and Height of Plant in cm on y axis. The scales on both x and y axes are shown from 0 to 5 at increments of 5. The graph shows dots at the ordered pairs 0, 1 and 0.5, 1.5 and 1, 2 and 1.5, 2.5 and 2, 2.8 and 2.5, 3 and 3, 3.4 and 3.5, 3.5 and 4, 4 and 4.5,4.5 and 5, 5. A straight line joins the ordered pairs 0, 1 and 5, 5

What would most likely be the approximate height of the plant after 8 weeks?

11.0 centimeters
9.25 centimeters
8.8 centimeters
7.4 centimeters

Four graphs are shown below:

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 negative linear association between x and y?
