Question

On a graph what quadrants are the points (0,4) (0,-4) (4,0) (-4,0) in?

Answer 1

They are all on the border of two quadrants (the `xandy` axes are the borders).

Explanation:

`(0,4)` is on the `y`-axis and above the `x`-axis, so it is between the first and second quadrant (`IandII`)
`(0,-4)` is on the `y`-axis and below the `x`-axis, so it is between `IIIandIV`
`(4,0)` is on the `x`-axis and to the right of the `y`-axis, so it is between `IVandI`
`(-4,0)` is on the `x`-axis and to the left of the `y`-axis, so it is between `IIandIII`

Usually these border-cases are assign to the lower quadrant of the two, so the answer would be `I,III,I,II`
