Coordinates part two

When coordinates are given in pairs, which they often are, they are COordinates after all, we need two number lines, or axes, to show the position of a point.

Paired coordinates are given between brackets, with a comma separating them, like this (-3, 0) or this (4, -2).

The x-coordinate is given first and the y-coordinate is given second (x, y). This makes sense, x comes before y in the alphabet.

With paired coordinates, the origin is (0,0)

(-3, 0) is -3 on the x-axis and 0 on the y axis

(4, -2) is 4 on the x-axis and -2 on the y axis.
