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.

EQUATION OF A STRAIGHT LINE
DEFINITION THE EQUATION OF A LINE THROUGH THE ORIGIN WITH A GIVEN GRADIENT 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

Generally, Parallel lines have the same gradient” the gradient of the perpendicular line is: a1 = -1/2
