Analytic Geometry in the Plane
Consider the Cartesian rectangular coordinate system in the plane. Taking the projection of any point ╠1 on the x and y coordinate we obtain two numbers x=a1 and y=b1. Take two numbers a2 and b2 plot a2 on the x-axis and b2 on the y-axis . Having drawn two straight lines parallel to the coordinate axes through these points we find obtain a point M2 in their intersection.
|| Thus, there is a oneľtoľone correspondence between points in the plane and pairs of numbers.
