Mathematics 20-1 Module 4

Module 4: Quadratic Equations and Inequalities

 

Refresher

 

Use the Solving Linear Systems by Graphing tutorial to review the following:

  • Define a system of equations.

  • Review the significance of the point of intersection as it relates to a system of equations.

  • Determine the solution to a system of linear equations by graphing.

  • Review how to verify the solution to a system of equations.
This is a play button that opens Solving Linear Systems by Graphing.

If you encounter difficulties working with the mini-explorer, you may want to use your own graphing technology instead.

 


This is a play button that opens Linear Systems Graph.

Linear Systems Graph can be used to help graph and solve systems of linear equations.

 


This is a play button that opens Given Two Points on the Graph.

Use the interactive lesson entitled Given Two Points on the Graph to practise writing equations of linear functions. Select Determining the Equation of a Line. Then choose Given the Slope and a Point. Work through slides 1 to 9 only.
