AlgebraEasy–MediumSlope of a horizontal line through two points
Algebra practice question
In the xy-plane, the graph of a linear function passes through the points (−3, 7) and (5, 7). What is the slope of the graph?
Answer: 0
Slope = (7 − 7)/(5 − (−3)) = 0/8 = 0. The line is horizontal.
Common wrong answers
- If you answered 7
- 7 is the constant y-value, not the slope.
- If you answered 8
- 8 is the run between the points.
- If you answered -3
- −3 is an x-coordinate, not the slope.
