On a graph paper, mark the points A(-1, -1) and B(2, 5). Draw a straight line passing through A and B. If points (m, 4) and (0.5, n) lie on this line, use graphical method of finding the values of m and n.

A triangle is formed by the straight lines x + 2y - 3 = 0, 3x - 2y + 7 = 0 and y + 1 = 0. Find graphically :

(i) the co-ordinates of the vertices of the triangle.

(ii) the area of the triangle.

If A = (x, -7), B = (2, 5) and AB = 13 units, find x.

A is a point on x-axis, B = (5, -4) and AB = 5 units, find the co-ordinates of A.
