9-60.

Cisco was looking at a table of values from a silent board game of *y* = *x*^{2}. She said, “*This table contains* (0, 0), *so I think it shows a proportional relationship.*” Is Cisco correct? Why or why not? Homework Help ✎

Proportional relationships do contain the point (0,0), but is she sure that the graph makes a straight line or that the table has points with corresponding ratios?

Examine the graph of *x*^{2} to the right.

Why is Cisco incorrect?
