# what is solve the system by graphing ⚑ Flag

by Mila009 at October 28, 2009

Well, I'd have to say that this question is a little vague.... but let me read your mind. I'm guessing you have a few equations like: y= 2x y= 3x - 2 .... y = x...etc Now in order to solve for the system by graphing you are actually going to plot these equations on an x-y plane. And the point where all of these lines intersect will give you a solution (x,y) where x and y are numbers. If you don't know how to graph equations search the math section above for "graphing equations"

I'm a bit confused by your question, but I agree with the answerer below.  You need to solve the equation for a variety of x values (provided that its in y equals) by using an x/y plot and then (solving the equation if you dont have one yet) plotting it on a graph.  Then all you have to do is plug in the x value that your solving for and viola! you have your answer.    I'm sorry, that probably made no sense.  Do you have an example problem, your question is a bit vague

you basically draw the 2 lines (the system), and at the point where the lines intersect is the answer for them.
