H. Algebra 2: Slope

  • Slope can be defined as a rate of change represented by the following:

    • the change in Y / the change in X

    • rise/run

    • delta Y/delta X

    • Y2 - Y1 / X2 - X1

  • Use Y2 - Y1 / X2 - X1 if you are given two points

    • (X1, Y1) and (X2, Y2)


  • Slope-intercept form:

    • Y = mx + b

  • Point-slope form:

    • Y - Y1 = m (X - X1)

      • (X1, X2): = point

  • Standard Form: Ax + By = C
