Draw the graph of 4x - 3y + 12 = 0 and use it to find the area of the triangle formed by the line and co-ordinate axes. Take 2 cm = 1 unit on both axes.

Draw the graph of the following linear equation :

x - 5y - 4 = 0

Draw the graph of the equation y = 3x - 4. Find graphically

(i) the value of y when x = -1

(ii) the value of x when y = 5.

Draw the graph of 3y = 12 - 2x. Take 2 cm = 1 unit on both axes.
