Algebra II: Constant of Variation
by Texas Instruments

Published on August 30, 2010


Students explore how the constant of variation, k, affects the graph of direct and inverse variations.

Key Steps

  • Image

    Students explore the effects of a, the constant of variation. They will first use the Transformation Graphing app to change a and observe how the direct variation graph changes.

  • Image

    For the application problem about direct variation, students will use a graph of the function and a point on the graph to determine the amount of money the employee will make for a certain number of hours.

  • Image

    Students will investigate the effect of a on the graph of an inverse variation using the left and right arrow keys.
