alleryThe co-ordinates of a point are written in the order
A(slope, intercept) by convention
B(y-coordinate, x-coordinate)
C(distance, angle) by convention
D(x-coordinate, y-coordinate)
Answer & Solution
Correct answer: D. (x-coordinate, y-coordinate)
1. A point is described by an ordered pair of numbers.
2. The convention is: x first, then y.
3. So co-ordinates are written as (x, y).
4. Hence option A is correct.
