Question

Which one doesn’t belong? Select a graph and give a reason why you selected the shape. Are there any other graphs that do not belong? Why or why not?

Answer 1

Graph 4

Explanation:

Graph 4 does not belong. This is as a result of the fact that it Graph 4 has a negative slope(descends) while all other graphs have a positive slope(ascends).

Another way to view it is that the values in Graphs 1, 2 and 3 are directly related while the values in Graph 4 are inversely related.
