How do you solve 2x-4y 4 and 3x-y 4 using a graph? - Answers

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals".The graphics facilities available to us are worse than pathetic so you will have to do with a descriptive answer.Plot the graph of 2x -4y = 4 (I am assuming that there is a "=" sign there). To do this, cover up "-4y". This leave 2x = 4 and, on dividing by 2, x = 2. Thus x=2, y=0 or (2, 0) is one point on the graph. Next cover up "2x", which leaves -4y = 4 so that y = -1 and so (0, -1) is another point on the graph. Mark these two points on a coordinate plane, join them together with a straight line and extend the line in both directions.Repeat for the second equation. The two lines will intersect and th coordinates of their point of intersection is the solution.Further Information:If you mean: 2x-4y = 4 and 3x-y = 4Coordinates of 1st line: (2, 0) and (0, -1)Coordinates of 2nd line: (4/3x, 0) and (0, -4)Graph the two lines on the Cartesian plane and where they intersect are the solutions to the equations which works out as x = 1.2 and y = -0.4
