Ordered Pairs• An ordered pair comes in the
form (x,y) with x always first and y always second
• The x value refers to the numbers on the x axis
• The y value refers to the numbers on the y axis
Coordinate Plane• The coordinate plane consists of 4
quadrants
• Starting in the upper right hand corner with quadrant 1 and moving counterclockwise to quadrant numbers 2, 3, & 4.
• There are 7 different places in the coordinate plane. What are they?
Plotting Points• To plot a point on the x,y axis, always
start at the origin.
• Using the x value, move left or right on the x axis depending on whether the x value is positive or negative.
• Using the y value, move up or down on the y axis depending on whether the y value is positive or negative.
More on plotting points• For every 1 point on a graph it
takes two numbers to identify the correct location.
• Think of a game of Bingo as it needs both a letter and a number to identify the correct square.
