Question
If the co-ordinate of A is x and that of B is y, find d(A, B).
x = - 3, y = 7
Solution
It is known that the 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 = 7.
We know that 7 > −3.
∴ d (A, B) = 7 − (−3)
∴ d (A, B) = 7 + 3
∴ d (A, B) = 10
