Ex 6 3 2 Solve 3x 2y 12 X 1 Y 2 Graphically Graph of 2x y 1 = 0 and 2x y = 9 on the same axes Use 2 cm = 1 unit on both axes and plot only 3 points per line Write down the coordinates of the point of intersection of the two linesThe coordinates of the point of intersection would be the solution to the system of equations If the two graphs do not intersect which means that they are parallel then there is no solution Example Using the graphical method, find the solution of the systems of equations y x = 3 3x-y=2 2x-y=3 graphical method
