Question
If the co-ordinate of A is x and that of B is y, find d(A, B).
x = -4, y = -5
Advertisements
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 = -4 and y = -5.
We know that -4 > -5.
∴ d (A, B) = -4 - (-5)
∴ d (A, B) = - 4 + 5 = 1
