There are many ways to think fundamentally about the concept of mathematics. One way is to separate the subject into how to write math (oftentimes, algebra) and how to draw it (oftentimes, geometry). A coordinate plane graph lives in the space between writing and drawing mathematics, as the graph can often be described both by written equations and visual shapes.
In the U.S., students in Grades 5 and up typically first learn to perform x- and y-axis graphing on a coordinate plane. Once they are ready for positive and negative integers, often by Grade 6, you can extend graphing to all four quadrants of the coordinate plane.

Points on a Grid
A location, or point, on a grid can be identified by an ordered pair such as (3,2), which names the coordinates of that point. The first number tells how far to the right or left the point is located in the horizontal direction. The second number tells how far up or down the point is located in the vertical direction. Note that the point (3,2) is not the same as point (2,3). The numbers in an ordered pair are called coordinates.
