(x, y)

x y quadrants first quadrant second quadrant third quadrant fourth quadrant

x y Signs (+,+)(-, +) (-,-)(+,-)

x y “origin” (0,0)

x y Ordered Pair (5, 4) Coordinate Plane “origin” (0,0)

x y Ordered Pair (5, -4) Coordinate Plane “origin” (0,0)

x y Ordered Pair (-5, -4) Coordinate Plane

x y Graph (-5, 4) (-5,4)

x y (-3, 3) What are the coordinates? Which quadrant?

x y (5, -2) What are the coordinates? Which quadrant?

x y What are the coordinates? Which quadrant? (1,1)

 A set of ordered pairs  Example: { (1,2), (3,4), (5,1)}

RelationTable  { (1,2), (3,4), (5,1)} xy

 The x- coordinates in a relation. Example: Find the domain of { (1,2), (3,4), (5,1)} The domain is {1,3,5}

 The y-coordinates in a relation. Example: Find the Range of { (1,2), (3,4), (5,1)} The Range is {2,4,1}

 Make a table of ordered pairs in which the x- coordinate represents the hours and the y-coordinate represents the amount of money John earns for 1, 2, 3, and 5 hours of work. Hours (x)$$ (y)

 Graph the table on your graph paper. Describe the graph.  Is it increasing from left to right? yes  Is it decreasing from left to right? no  Does John make more money the more hours he works? yes

 Label from 10 to -10 on both x and y axis for your battle zone and your partner’s battle zone

 Plot your ships on “My Battle Zone”: (has to be consecutive either up down, left, right or diagonal) ◦ Destroyer (, ) & (, ) ◦ Submarine (, ) & (, ) & (, ) ◦ Cruiser (, ) & (, )& (, ) & (, ) ◦ Battleship (, )& (, ) & (, ) & (, ) ◦ Carrier (, )&(, ) & (, )&(, )& (, ) Cover your paper as you do this!

 Take turns (rock paper scissor who goes first)  X-hit  0- miss  Mark for both your battle zone and your opponents  If a player says an ordered pair twice they loose a turn  If you get a hit you keep guessing until you miss.

 Objective is to sink all of your opponents ships  Both you and your opponent will turn in your graphs for class work points.

Cartesian Battleship Please follow directions and be honest! x y Directions 1) Draw your ships in your battle zone 2) List the coordinate s of your ships 3) Pick a command 4) Mark your sheet Command Use a radar on an axis or quadrant Fire at a coordinate
