How Do You Use A Graphing Calculator To Solve A Systems Of Equations?
• Convert the equations into y= form In order to graph an equation on your calculator, the left side of the equation must only contain y. This is pretty easy to do, especially if you are dealing with linear equations. All you have to do is solve your equation for y. If it is a linear systems in standard form (Ax+By=C), then you can just write down the following equation, subbing in for the constants A, B, and C: y=(c-ax)/b or you can use the second method. If your equations are in slope intercept form, you already have the equation in y= form. • Plug the equations into your calculator. Press the y= button, usually the top left button on your calculator, and type in your first equation under y1 and your second equation under y2. Since you can only use 2 variables with this method, you shouldn’t need more than 2 equations. If instead of y=, you have something else, make sure you are in function mode by pressing the mode button and making sure “Func” is highlighted. • Make sure all plots
