To Start: Simplify the following: -5(2)(-4) -4(-3)(6) -6(2)(-1) = 40 = 72 = 12

Chapter 1: Algebraic Expressions and Integers Section 1-10: The Coordinate Plane

II I III IV The Coordinate Plane The x and y axis divide the coordinate plane into 4 quadrants. The origin is where the x and y axis intersect. II I III IV

Ordered Pair An Ordered Pair gives the coordinates and location of a point. (-5,-4) The x-coordinate The y-coordinate
