 Posted by dsteph02 at Dec 16, 2006 5:44:57 PM How do I graph 2 equations? How do I graph 2 equations to find the break even point? And I need help understanding what this means "In the equations (C=800+3.20N and R=8.50N) do the y-intercept and coefficient of N give you?"

 Posted by pskinner at Dec 16, 2006 7:27:39 PM Re: How do I graph 2 equations? Question: "How do I graph 2 equations to find the break even point?"Answer: You can rewrite the equations, substituting x and y for the variables you might have (so if c=800+3.20N, replace c with y and N with x: y=800+3.20x; and if R=8.50N, replace R with y and N with x: y=8.50x). Then you can use the "Basic Multiple Equations & Systems Plotting Calculator", entering each equation as above separated by commas. Where they intersect will be the so-called break even point.In your second question, there must be some typographical error because I can't decipher what it means. ---------------------------------------- Principal Skinner
