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.
