Question

In which quadrants do the x-coordinates and the y-coordinates have the same sign?

Answer 1

In the First quadrants and the third quadrants have the same sign of the x-coordinates and the y-coordinates which is I (+; +), III (−; −).

According to the statement

we have to find that the in In which quadrants do the x-coordinates and the y-coordinates have the same sign.

For this purpose, firstly we know that the

Quadrants are The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes. These are often numbered from 1st to 4th and denoted by Roman numerals.

And according to the Cartesian system, we know that the

First quadrants have a sign :

I (+; +),

And second quadrants have a sign:

II (−; +),

And third quadrants have a sign:

III (−; −),

and Fourth quadrants have a sign:

IV (+; −).

So, In the First quadrants and the third quadrants have the same sign of the x-coordinates and the y-coordinates which is I (+; +), III (−; −).
