Algebra practice question

In the xy-plane, the graph of a linear function passes through (0, 5) and (2, 5). What is the slope of the graph?

Answer: 0

The y-value does not change, so the slope is (5 − 5)/(2 − 0) = 0.

Common wrong answers

If you answered 2
2 is the change in x.
If you answered 5
5 is the constant y-value, not the slope.
If you answered 2.5
2.5 divides 5 by 2.
