- Draw the graph of 3y=12 -2x. Take 2 cm =1 unit on both axes
- use graph paper for this question. draw the graph of 3x-2y=5 and 2x=3y on the same axes. use 2cm=1 unit on both the axes and plot only 3 points per line. write down the coordinates of the point of intersection of the two lines. also find the area of the triangle formed by the lines and the y axis
