If p, q and r are in AP, then the points X, Y and Z are
For the next two (02) items that follow : Let X(a, p), Y(b, q) and Z(c, r) be the points such that a, b and c are in AP.
- A. on a straight line ✓
- B. on a circle
- C. on a parabola
- D. the vertices of a triangle
Correct Answer: A. on a straight line
Explanation
The differences between the x-coordinates (b-a = c-b) and the y-coordinates (q-p = r-q) are constant. This ensures the line segments have equal slopes, meaning the points are collinear.
