Concept Recap

An exact location in space with no size, length, or width—zero dimensions; named with a capital letter.

The tip of a pencil or a dot on a map. Position only, no width or length.

  • Try the practice problems before revealing each solution.
  • Use the related concepts and background knowledge badges if you feel stuck.

What to Focus On

Core idea: A point marks an exact position in space, with zero length, width, or thickness.

Common stuck point: The procedure for point is the easy part; the trap is treating a point as a small dot with size. Asking "Am I naming just a location, with no length, width, or size?" first is what keeps a correct-looking calculation from being attached to the wrong concept.

Sense of Study hint: Ask: Am I naming just a location, with no length, width, or size?

Worked Examples

Example 1

easy
Plot the point (3,2) on a coordinate grid and describe its location.

Answer

The point (3,2) is 3 units right and 2 units up from the origin.

First step

1
Step 1: Start at the origin (0,0).

Full solution

  1. 2
    Step 2: Move 3 units to the right along the x-axis.
  2. 3
    Step 3: Move 2 units up along the y-axis.
  3. 4
    Step 4: Mark that location with a dot — this is the point (3,2).
A point has no size, no length, no area — it is simply a location in space. On a 2D coordinate grid, every point is uniquely identified by an ordered pair (x,y).
