Graphing Lines with a TI-83/84 Calculator

This video tutorial demonstrates how to graph lines using the TI-83 or TI-84 graphing calculators. It covers entering equations in slope-intercept form, setting the standard viewing window, and using the table feature to find exact points for plotting. The tutorial also explains handling fractional slopes and solving equations for Y when not in slope-intercept form. The video provides a step-by-step guide to ensure accurate graphing and verification of plotted lines.

What is the preferred form of an equation to enter into the TI-83/84 calculator for graphing?
