Coordinate GeometryInequalityGraphing
This example demonstrates how to graph the solution set of linear inequalities in a coordinate plane. Key math concepts include linear equations, inequalities, region representation, and coordinate geometry. It uses GeoGebra commands/objects a, b, c, k, l, d to define line equations and inequality boundaries, with shaded regions indicating solutions. Suitable for high school students learning the geometric meaning and practical applications of linear inequalities.

GeoGebra Commands & Parameters

  1. Numeric a(0.5)
  2. Numeric b(0.5)
  3. c(x, y) = y > (a * x) + b
  4. Numeric k(-1.2)
  5. Numeric l(1.0)
  6. d(x, y) = y ≤ (k * x) - l
