Graphing Linear Equations (Slope Intercept Form)

The original idea for creating this applet comes from [url=https://www.geogebra.org/stevephelps]Steve Phelps[/url]' [url=https://www.geogebra.org/m/WVGxwKKn]Graph the Line[/url] applet. [br][b][color=#cc0000][br]Directions:[/color][/b][br][color=#0000ff][br][/color][color=#000000]1) Examine the equation shown on the right side of the screen. [/color][br]2) [b]Reposition the 2 big points so that the line is the graph of the displayed equation. [br][/b]3) Click the "Check Answer" checkbox to check. [br][b] [color=#ff00ff]If you're correct, the applet will inform you.[/color] [br][/b][b] If you're not, you'll know this as well. [/b][color=#000000][br] If you're not correct, keep trying until you position the gray line correctly.[br][br][/color]4) After correctly graphing the line, click the "Generate New Line" button.[br][b][color=#0000ff][br]Repeat steps (1) - (4) as many times as you need until you've mastered this concept.[/color][/b]

Writing Linear Equations (Given Graph)

[color=#cc0000][b]Students:[/b][/color][br][br]For the line displayed, write the slope-intercept form of its equation in the input box below. [br][color=#3c78d8][b]For some problems, you may need to ZOOM OUT in order to see the black point on the line. [/b][/color][br][color=#ff00ff][b]If you enter this equation correctly, you'll see a big "CORRECT"! text appear. [/b][/color] [br][br][color=#0000ff][i]Repeat this exercise as many times as you need in order to master this concept! [/i][/color]

Writing Linear Equation (Given Both Intercepts)

[color=#cc0000][b]Students: [/b][/color][br][br]In the applet below,[br][br]1) Write the slope-intercept form of the equation of the line with the given intercepts. [br]2) [color=#ff00ff][b]If you enter in a correct equation, you'll see a big "CORRECT !!!" sign appear. [/b][/color] [br]3) [color=#0000ff][i]Repeat steps (1) - (2) as many times as you need in order to master this concept! [/i][/color]
