Point Definition: an x-value and y-value that can be located on the coordinate plane; it indicates a location Examples: (3, 4)  Quadrant 1 ( x positive, y positive) (-3, 4)  Quadrant 2 (x negative, y positive) (-3, -4)  Quadrant 3 (x negative, y negative) (3, -4)  Quadrant 4 (x positive, y negative)
