D. Graphing Linear Relations Using Technology

Many calculators and computer programs are capable of graphing linear relations from an equation. Typically, you will enter the right side of an equation of the form y = mx + b. You may need to adjust the axis size and scale to see the graph of the relation properly. For instructions on how to graph a relation, either refer to your calculator's instruction manual or enter "graphing relations using [the name of your graphing calculator or graphing program]" into a search engine. If you have difficulty graphing relations with technology, contact your teacher.

Detailed instructions for graphing using a TI-83 â„¢ and TI-84 â„¢ calculator can be found in the Appendix.

Some graphing programs are limited to functions. That is, they can only graph equations of the form 'y =___'. In the next lesson, you will see that some linear relations cannot be written in this form. These relations cannot be graphed by a program limited to functions.
