What is the X-Coordinate?

Definition: X-Coordinate

Summary

  1. The x-coordinate is the first number in an ordered pair
  2. Here the x-coordinate is 3
  3. The x-axis is the horizontal line of the coordinate axes
  4. The x-coordinate tells us where to move on the x-axis
  5. If the x-coordinate is POSITIVE we move to the RIGHT
  6. If the x-coordinate is NEGATIVE we move to the LEFT
  7. Since our x-coordinate was positive 3, we moved 3 units to the RIGHT

Notes

    1. So in (3,4), the x-coordinate is 3
    1. The x-coordinate tells us how many units we move to the LEFT or RIGHT
    2. Since 3 is POSITIVE, we move RIGHT 3 units
    1. The y-coordinate tells us how many units we move UP or DOWN
    2. Here the y-coordinate is 4, so we move UP 4 units
    1. The x-axis is the horizontal line of the coordinate axes
    2. The number of the x-coordinate tells us how many units we're moving
    3. The sign of the x-coordinate tells us which direction we're moving
    1. On the x-axis, numbers increase from LEFT to RIGHT
    2. So moving to the RIGHT takes us in a POSITIVE direction
    1. On the x-axis, numbers increase from LEFT to RIGHT
    2. So moving to the LEFT would take us in a NEGATIVE direction
    1. The number of the x-coordinate tells us how many units to move
    2. If the x-coordinate is POSITIVE we move to the RIGHT
    3. If the x-coordinate is NEGATIVE we move to the LEFT
