This example demonstrates the effect of changing m and c on the graph of a linear equation. It covers the core concept of the gradient-intercept form, including slope and y-intercept. Constructed using GeoGebra commands, including slider animation. Suitable for middle school and above students learning linear equations.

GeoGebra Commands & Parameters

  1. Numeric m(3)
  2. Numeric c(5)
  3. y = (m * x) + c
  4. Line c_1(-4, 1, 0)
  5. Line d(-0.25, 1, 0)
  6. Line e(1, 1, 0)

AI Drawing Prompt Reference

Draw a line with a slope of 3 and y-intercept of 5. Then, create two new lines with slopes of -0.25 and 1, respectively, both passing through the point (0,1). Observe how these lines affect the graph.
