Topics in Coordinate Geometry

1

Basic Concepts and Terminology

  • A point's position in a plane requires two pieces of information (like street number and house number)
  • The Cartesian plane uses two perpendicular number lines called coordinate axes
  • The horizontal line is the x-axis, vertical line is the y-axis
2

Plotting and Reading Points

  • To plot a point (x, y): move x units along x-axis, then y units parallel to y-axis
  • Positive x means right, negative x means left
  • Positive y means up, negative y means down
3

Points on Coordinate Axes

  • Any point on x-axis has y-coordinate = 0, so form is (x, 0)
  • Any point on y-axis has x-coordinate = 0, so form is (0, y)
  • Origin is the only point that lies on both axes: (0, 0)
4

Quadrants and Sign Patterns

  • Quadrant I: Both x and y are positive (+, +)
  • Quadrant II: x is negative, y is positive (-, +)
  • Quadrant III: Both x and y are negative (-, -)
