5.1 Understanding Linear Functions

Lesson: To graph linear equations written in standard form by treating them as a function that generates ordered pairs.
Any algebraic equation that can be converted to the form [color=#0000ff]Ax + By = C[/color] (A and B not both equal to 0) is a [color=#0000ff]linear equation in standard form[/color].[br][br]There is a postulate in Geometry that [color=#0000ff]'two points determine a line.'[/color] So it's possible to graph a linear equation by identifying two points that lie on the line. [br][br]A linear equation in [i]standard form[/i] is displayed at the upper left corner of the applet below. [br][br][b]Procedure for Interacting with The Applet and Turning in Your Work[/b][br][br]1) On a sheet of paper, isolate y in the displayed equation. [br][br]2) Assign a small input value to x which yields an output value to y resulting in an ordered pair. Repeat to[br] get another ordered pair. [Note: The applet only works for integer values of x and y.][br][br]3) Move the [color=#b45f06]2 Large White Dots[/color] to match your two ordered pairs.[br][br]4) Click [color=#351c75][b]Check Graph[/b][/color]. If you didn't get it right, check your calculations and try again. [br][br]5) Once you get a problem [color=#e06666][b]Correct[/b][/color], screenshot your work and upload to a Google Doc.[br][br]6) Click the [color=#38761d][b]New Problem [/b][/color]button and repeat steps 1 through 5 four more times. The Google Doc now[br] has 5 different graphs on it. Upload it to Google Classroom for this assignment. [br]
