1 Day 16 Lecture 14 Cartesian Graphs STUFF I WANT YOU TO KNOW You can ______________ to any point in the plane with two _____________ directions. It’s a lot nicer if those directions are _______________ since traveling in one of the two directions only affects the orthogonal _____________ onto that direction and not the other. 2 0

2 STUFF I WANT YOU TO KNOW, part 2 The Standard directions for coordinatizingthe plane are called _____, represent Up/Down or North/South , and _____, representing East/West or Left/Right . When Real Numbers Lines pointing in these directions are joined at the position ____ the result is the _____________ plane 3 0 Subtle Details Every point in the Cartesian Plane has a pair of Coordinates given by an _____________ pair, A point with coordinates (x, y) means one should start at ____and travel ________ units along the _____ direction (x-axis) and travel ________ units along the _____ direction (y-axis) to reach the point. The point with coordinates (0, 0) is called the ___________. If we change where the Origin is, the coordinates of the point also change 4 3
