Find the equations of the lines, whose :

(i) slope = - 4 and y-intercept = 2

(ii) slope = 0 and y-intercept = -5

(iii) slope = 3 and y-intercept = 4

(iv) slope = 1 and y-intercept = -5.

Solve, graphically :

2x - 3y = 7
5x + y = 9

Draw the graph of straight line y = -2x + 3. Use your graph to find :

(i) the intercept on y-axis

(ii) the area between the line and co-ordinate axes.

Find graphically the vertices of the triangle whose sides have the equations 2y - x = 8, 5y - x = 14 and y - 2x = 1. Take 1 cm = 1 unit on both the axes.
