A straight line passes through the points (2, 4) and (5, -2). Taking 1 cm = 1 unit; mark these points on a graph paper and draw the straight line through these points. If points (m, -4) and (3, n) lie on the line drawn; find the values of m and n.

Draw the graph (straight line) given by equation x - 3y = 18. If the straight line drawn passes through the points (m, -5) and (6, n); find the values of m and n.

For line y = 20 + 2x, if x = 20, the value of y is :

1. 40

2. 60

3. 80

4. 0

A point that lies on the line 2x - 3y = 4 can be taken as :

1. (-5, -2)

2. (-5, 2)

3. (5, 2)

4. (5, -2)
