What is the Y-Coordinate?

Definition: Y-Coordinate

Summary

  1. The y-coordinate is the second number in an ordered pair
  2. When graphing points we always start at the origin
  3. The 3 is positive so we move to the right 3 units on the x-axis
  4. The 4 is positive so we move up 4 units
  5. Mark that spot with a dot, and label it as the ordered pair (3,4)
  6. We went up 4 units on the y-axis because our y-coordinate is positive 4!

Notes

    1. For our example, (3,4), the y-coordinate is the 4
    1. If the 3 were negative, then we would first move the the left on the x-axis, instead of moving right
    1. If the 4 were negative, then we would move down, instead of moving up
    1. If the y-coordinate is positive we move up, and if it is negative we move down
