How it works ?
You can use this applet to check your work of graphing 2-variable linear inequalities by hand. (Do so AFTERWARDS!)
Note the inequality is written in standard form: Ax + By ??? C.
You can choose the parameters A, B, C (by entering values or using the slider). Applet only takes parameter values from -50 to 50 (inclusive). You can choose the appropriate inequality symbol as well.
