Year 8 Coordinates: Quadrants, Midpoints and Distance Worksheet — Level 2 — Practice Set 4 — Answers
Midpoint = (average of the x-values, average of the y-values). Distance: use Pythagoras with the horizontal and vertical changes.
Answer: (3.5, −8.5)
- x: (5 + 2) ÷ 2 = 3.5
- y: (−9 + (−8)) ÷ 2 = −8.5
Answer: (5.5, 0.5)
- x: (4 + 7) ÷ 2 = 5.5
- y: (−6 + 7) ÷ 2 = 0.5
Answer: (1, 3)
- x: (−4 + 6) ÷ 2 = 1
- y: (4 + 2) ÷ 2 = 3
Answer: (2.5, −2)
- x: (8 + (−3)) ÷ 2 = 2.5
- y: (−7 + 3) ÷ 2 = −2
Answer: (4.5, 0)
- x: (4 + 5) ÷ 2 = 4.5
- y: (2 + (−2)) ÷ 2 = 0

Answer: first
x is positive and y is positive, so the point is in the first quadrant.
Answer: (2, 3)
- x: (−5 + 9) ÷ 2 = 2
- y: (8 + (−2)) ÷ 2 = 3
- Afirst
- Bsecond
- Cthird
- Dfourth
Answer: second
x is negative and y is positive, so the point is in the second quadrant.

Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
