Plotting points

Math

Definition

The process of marking locations on a coordinate plane using ordered pairs (x, y). Start at the origin, move horizontally by the x-value, then vertically by the y-value.

How It Works

  1. Start at the origin (0, 0)
  2. Move right for positive x or left for negative x
  3. From that position, move up for positive y or down for negative y
  4. Place a dot at the final location

Examples

  • Plotting (3, 4): go right 3, up 4
  • Plotting (-2, 5): go left 2, up 5
  • Plotting (0, -3): stay at center horizontally, go down 3
