Coordinate Plane

X-Axis (Horizontal)

Y Axis (Vertical)

Origin (0,0) where x and y axes cross

Ordered Pair (x, y) identifies a location on the coordinate Plane

Quadrants: I. (+ +)   II. (-, +)  III. (-,-)    IV. (+, -)

Distance | x2 - x1| or |y2 - y1|

OR Add values when you cross Quadrants:  |x2| + |X1| or |Y2| + |Y1|

Subtract when you are in a quadrant: |x2| - |x1| or |Y2 |- |Y1|

(When you cross an Axis, on of the signs will be Negative, SO: x2 - (-x1) -> (X2 + X1) 

Distance is not (-) negative so the Absoulte Value (| q | is used.

REFLECTION: Over X:   (x, y) Becomes (x, -y)

Reflection Over Y:        (x, y) Becomes (-x, Y)

Over both (X, Y):          (x, y) Becomes (-x, - y)

NORTH = UP  + Y

EAST = RIGHT + X

SOUTH = DOWN ( - Y)

WEST = LEFT ( - X)
