Quick Reference

• Linear relationships
  In many business applications, two quantities are related linearly. This means a graph of their relationship forms a straight line. This leaflet discusses one form of the mathematical equation which describes linear relationships.
• The slope-intercept form
  This leaflet explains the slope-intercept form of an equation describing a straight-line.

Teach Yourself

• Linear functions
  Some of the most important functions are linear. This unit describes how to recognize a linear function, and how to find the slope and the y-intercept of its graph.

Test Yourself

• Diagnostic Test - Linear functions and graphs
• Exercise - Linear functions and graphs

Video

A transcript of each video should be available in the Teach Yourself section above.

These videos require Windows Media Player (v10).

Please note: You may experience trouble with more recent upgrades to Internet Explorer (now v.7) and Media Player (now v.11). These no longer support streaming from the mms servers used by mathcentre, so we are recommending that you uninstall IE7 (IE6 lies underneath) and replace the new version of WMP with the fully functioning v.10 (you may need to find a download via google after uninstalling v.11). All those that have done this have reported back that everything is working again.
