Practice Question
Two points (a,b) and (c,d) are shown on a graph. Which of the following equations correctly represents the slope of the line that passes through these points.
Answer Choices
- A: (b-d)/(a-c)
- B: (d-b)/(c-a)
- C: (b-d)/(c-a)
- D: (d-b)/(a-c)
Correct Answer: B
Rationale: Slope = (y2 - y1)/(x2 - x1) = (d - b)/(c - a). Thus, the correct answer is (d-b)/(c-a).
