Coordinate Geometry (L.A.G.)

By: Stephen C. & Donavan D.

Definition

  1. The plane determined by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis, intersecting at a point called the origin. Each point in the coordinate plane can be specified by an ordered pair of numbers.

Example 1

The X axis always comes first, then the Y axis. Like (9,-4) the 9 is the X axis and the -4 is the Y axis

Additional Info.

Coordinate Planes are used for graphing data on points.


Midpoint Formula (X,Y)=[(X1+X2) Y1+Y1)]

----------------------

2 2


Slope Formula M= Y2-Y1

---------

X-2 - X1


Distant Formula D=v----------------------

(X2-X1)^2+(X2 - Y1)^2
