IDENTIFY AND PLOT POINTS IN ALL FOUR QUADRANTS • A point can be marked on a grid by using pairs of numbers called coordinates. • In a coordinate pair, the first number indicates the position of the point along the horizontal axis of the grid. The second number indicates the position of the point along the vertical axis. • The place where the horizontal and vertical lines meet, indicated by the coordinates, is the location of the point. • Because a grid can have both positive and negative numbers on each axis, there are 4 quadrants or sections on any grid. Quadrant B has pairs of positive numbers Quadrant C has pairs of negative numbers Quadrant A has a negative number first and then a positive number Quadrant D has a positive number first and then a negative number © Copyright NewPath Learning.

How to identify and plot points in all four quadrants: • The first number in a coordinate indicates the point’s position along the horizontal axis • The second number in a coordinate indicates the point’s position along the vertical axis • Start by locating the point’s position along the horizontal axis • If the first number is a positive number, the point will be located to the right of the vertical axis. If it is a negative number, the point will be located to the left of the vertical axis. • If the second number is positive, the point will be located above the horizontal axis and if the second number is negative, the point will be located below the horizontal axis. • Start by finding the position of the point along the horizontal axis. Then, use the second number to place the point above or below the horizontal axis. Examples: The point (5, 4) is located five squares to the right of the vertical axis and 4 squares above the horizontal axis. Therefore, it is in quadrant B. The point (6, -3) is located 6 squares to the right of the vertical axis and 3 squares below the horizontal axis. Therefore, it is in quadrant D. The point (-4, 7) is located 4 squares to the left of the vertical axis and 7 squares above the horizontal axis. Therefore, it is in quadrant A. The point (-6, -5) is located 6 squares to the left of the vertical axis and 5 squares below the horizontal axis. Therefore, it is in quadrant C. © Copyright NewPath Learning. All Rights Reserved.
