Question
If the co-ordinate of A is x and that of B is y, find d(A, B).
x = 4, y = - 8
Advertisements
Solution
It is known that distance between the two points is obtained by subtracting the smaller co-ordinate from larger co-ordinate.
The coordinates of A and B are x and y respectively.
We have, x = 4 and y = − 8.
We know that 4 > − 8.
∴ d (A, B) = x − y
∴ d (A, B) = 4 − (− 8)
∴ d (A, B) = 4 + 8
∴ d (A, B) = 12
