 How can we graph functions?

 Named after French mathematician René Descarte.  Also called Cartesian Coordinate System  Also called Rectangular Coordinate System  Has an x-axis and y-axis  The origin is the intersection of the axes  The axes divide the plane into four quadrants  Each point corresponds to an ordered pair of two real numbers (x, y)

 Page 121 #1-45 Every Other Odd  You MUST use graph paper.

 In Exercises 1-12, plot the given point in a rectangular coordinate system.  Graph each equation in Exercises Let x={-3, -2, -1, 0, 1, 2, 3}.
