Concept of Coordinates
This is a system of geometry where the position of points on the plane is described using an ordered pair of numbers.
Recall that a plane is a flat surface that goes on forever in both directions. If we were to place a point on the plane, coordinate geometry gives us a way to describe exactly where it is by using two numbers.
DEFINITION

THE Y-INTERCEPT OF A LINE
THE EQUATION OF A STRAIGHT LINE WITH GIVEN GRADIENT, PASSING THROUGH A GIVEN POINT
THE EQUATION OF A STRAIGHT LINE THROUGH TWO GIVEN POINTS
