Answer:
<u>Question (a)</u>
Midpoint of a line segment:
Given:
- J = (-2, 2)
- L = (4, 0)
Given:
- M = (3, 7)
- K = (-1, -5)
<u>Question (b)</u>
Find slopes (gradients) of JL and MK then compare. If the product of the slopes of JL and MK equal -1, then JL and MK are perpendicular.
Given:
- J = (-2, 2)
- L = (4, 0)
Given:
- M = (3, 7)
- K = (-1, -5)
Hence segments JL and MK are perpendicular
