1) Solve graphically the following equations :

x+2y=4 , 3x -2y =4 . take 2cm = 1 unit on eachaxis. Write down the area of the triangle formed by the lines and the x- axis.

2) on graph paper take 2 cm to represent one unit on both the axes draw the lines:

x+3= 0, y-2=0, 2x+3y=12. Write down the coordinates of the vertices of the triangle formed by the lines
