On graph paper, take 2 cm to represent one unit on both axes, draw the lines :

x + 3 = 0, y - 2 = 0, 2x + 3y = 12.

Write down the coordinates of the vertices of the triangle formed by these lines.

Find graphically the coordinates of the vertices of the triangle formed by the lines y = 0, y = x and 2x + 3y = 10. Hence, find the area of the triangle formed by these lines.

Find the distance between the following pair of points :

(0, 0), (36, 15)

Find the distance between the following pair of points :

(a, b), (-a, -b)
