Objective Learn to use a graphing calculator to graph linear relations and equations.

This is an exploration lesson, both in using the graphing calculator and in introducing the relationship between the equation of a line and its graph.

Here are some examples.


Graph each pair of linear equations.

1) y = 3x + 7 and y = 2 - 5x

These equations are in slope-intercept form, so y is given explicitly in terms of x . This means that 3 x + 7 and 2 - 5 x can be entered directly into the calculator.

2) 4x + 3y = 5 and 7x - 2y = 1

In these equations, you must first solve for y, and then use the calculator.
