Distance Between Two Points on the Coordinate Plane: Sample FAST Questions

Finding the distance between two points in 8th grade means building a right triangle on the grid, not memorizing a formula. Students count the horizontal and vertical legs from the coordinates, then apply the Pythagorean Theorem to get the diagonal.

How the FAST tests this benchmark

The FAST uses graphic response items where students draw or identify the right triangle and equation editor items for the distance. The distance formula is not expected at this grade, and an answer can stay in radical form, such as √5 units.

Skills students need

  • Build a right triangle from two points on a grid
  • Find leg lengths from coordinate differences
  • Apply the Pythagorean Theorem to find a distance
  • Solve real-world coordinate distance problems
