All the points are located in the coordinate plane when we talk about coordinate geometry. It is all about the x-axis and y-axis.

Some basic concepts of Coordinate Geometry:

Origin is the point of intersection of the x and y-axis where both x and y are 0.

Always remember that on the right-hand side of the x-axis, the values are positive and on the left-hand side of the x-axis, the values are negative.

The same applies to y-axis where all the values located above the origin are positive and those located below the origin are negative.

A set of two numbers is used to locate a point on the plane which is written as the location on the x-axis initially, followed by its location on the y-axis. In union, the two will determine a unique position on the plane.

Here is a bit more you should know to solve Coordinate Geometry problems.
