Lesson Worksheet: Partitioning a Line Segment on the Coordinate Plane Mathematics

In this worksheet, we will practice finding the coordinates of a point that divides a line segment on the coordinate plane with a ratio using the section formula.

Q1:

  • B(1,1)
  • C(1,1)
  • D(1,1)

Q2:

The coordinates of 𝐴 and 𝐵 are (1,9) and (9,9) respectively. Determine the coordinates of the points that divide 𝐴𝐵 into four equal parts.

  • A(9,5), (9,7), (4,2)
  • B(5,9), (7,9), (3,9)
  • C(5,9), (7,9), (7,5)
  • D(5,9), (7,9), (2,0)
