When working with equations that have two variables, the coordinate plane is an important tool. It's a way to draw pictures of equations that makes them easier to understand. To create a coordinate plane, start with a sheet of graph or grid paper. Next, draw a horizontal line.
Collinear Points. There is an important branch of mathematics which is known as coordinate geometry. It is the study of position of geometrical figures in two or three dimensional space. When we start studying about coordinate geometry, we come across points and coordinates.
