Question
If the co-ordinate of A is x and that of B is y, find d(A, B).
x = -3, y = -6
Solution
It is known that distance between the two points is obtained by subtracting the smaller co-ordinate from the larger co-ordinate.
The coordinates of A and B are x and y respectively.
We have, x = -3 and y = -6.
We know that -3 > -6.
∴ d (A, B) = -3 - (- 6)
∴ d (A, B) = -3 + 6
∴ d (A, B) = 3
