Q1 of 29 Page 11

Select the correct alternative from the answers of the question given below.

Find d(A, B), if co-ordinates of A and B are - 2 and 5 respectively.

The coordinates of A and B are -2 and 5 respectively. We know that 5 > -2.

Thus, d (A, B) = 5 – (-2) = 5 + 2 = 7


So, the correct option is C.

On a number line, co-ordinates of P, Q, R are 3, - 5 and 6 respectively. State with reason whether the following statements are true or false.

i. d(P,Q) + d(Q,R) = d(P,R)


ii. d(P,R) + d(R,Q) = d(P,Q)


iii. d(R,P) + d(P,Q) = d(R,Q)


iv. d(P,Q) - d(P,R) = d(Q,R)
