This example demonstrates how to find the equation of a straight line given two points. Key mathematical concepts include the equation of a line, slope, and point-slope form. GeoGebra commands such as Line, Slope, and If are used to construct the graph. Suitable for students in middle school and above to learn how to find the equation of a straight line.

GeoGebra Commands & Parameters

  1. Line(A, B) → L
  2. Slope(L) → m
  3. If(m ≟ 1, "", "?", m ≟ -1, "-", m > 0, FractionText[m], m < 0, "-" + (FractionText[abs(m)]), m ≟ 0, "0") → textm
