The Cartesian Co-ordinate System
The plane with xy -axes is called the Cartesian Co-ordinate
System. It allows us to make a one-to-ne association between
points in the plane and ordered pairs of numbe

As we move along a straight line in the co-ordinate plane from
point to point, changes in y -coordinates and changes in x
coordinates are linked to one another.

By squaring out the terms and collecting the constants, we can
write
(x + 2)2 + (y 1)2 = 4
as
x 2 + 4 x + y 2 2y + 1 = 0
