[Mathematic Form 2] Stating & Plotting the coordinates of points

ALWAYS remember:
  • When stating the coordinates of a point, the x-coordinate is always written first, followed by the y-coordinate.

  • The x-coordinate of all points on the y-axis is always zero.

  • The y-coordinate of all points on x-axis is zero.
(x, y)
x =>
x-coordinate (x units from the y-axis)
y
=> y-coordinate (y units from the x-axis)


Example:

Plot the following point on the graph given.
  • P (3, 4)

  • Q (-2, 0)

  • R (4, -1)

  • S (0, 2)

  • T (-3, -3)

  • U (-1, 4)
