To the right of the y-axis, x-coordinates are positive.
To the left of the y-axis, x-coordinates are negative.
Above the x-axis, y-coordinates are positive.
Above the y-axis, y-coordinates are negative.

Instead of asking others for help, why don;t you explain what you didn't understand from my explanation?

anonymous · Answer

aren't the coordinates of a point a pair of numbers that define its exact location on a two dimensional plane which the coordinate plane has two axes that are right angles to each other (the x and y axis) which the coordinates of a given point represent how far each axis the point is located???
or their answer is good also i might just be throwing wrong information for all i know lol

The question is how to use the signs of the coordinates to determine the location of points.
If you only use the signs, the only thing you can tell is which quadrant a point is in. You can't tell the exact location. For the exact location, you need the exact coordinates.

For example, if the x- and y-coordinates are both positive, the point is in quadrant 1.
If the x-coordinate is positive, and the y-coordinate is negative, the point is i n quadrant 4.
