Coordinate Geometry

Exploring the Coordinate Plane

Coordinate geometry connects algebra and geometry by representing geometric shapes using equations on the \( (x, y) \) plane.

Key Topics

  • Distance formula: Find the length between two points.
  • Midpoint formula: Locate the center between two coordinates.
  • Equation of a circle and line.

Why It Matters

This approach helps you analyze shapes, find intersections, and solve for unknowns using algebra.

Tips

  • Sketch points and shapes to visualize problems.
  • Use formulas carefully—substitute values accurately.

Everyday Uses

Mapping apps use coordinate geometry to calculate distances and routes between locations.

Examples

  • The midpoint between (2, 3) and (6, 7) is (4, 5).

  • The equation \( (x-1)^2 + (y+2)^2 = 9 \) represents a circle centered at (1, -2) with radius 3.

In a Nutshell

Use equations and formulas to solve problems involving points, lines, and shapes on a plane.
