Opening your practice adventure…
Try a sample
Find the distance between (0, -1) and (5, 11) in coordinate units.
- 16
- 13
- 12
- 11
See the answer & why
13
The horizontal change is 5 and the vertical change is 12. Distance = √(52 + 122) = √169 = 13.
A little hint: Use the horizontal and vertical changes as the legs of a right triangle.
A teaching tip
The coordinate differences form perpendicular legs of a right triangle.
