Definition : Copyright © 2000 by Monica Yuskaitis Definition Coordinate grid – a grid used to locate a point by its distances from 2 intersecting straight lines. A B C D E 1 2 3 4 5 What are the coordinates for the house? Definition : Copyright © 2000 by Monica Yuskaitis Definition x axis – a horizontal number line on a coordinate grid. 1 2 3 4 5 0 6 x Hint : Copyright © 2000 by Monica Yuskaitis Hint x is the shortest and likes to lie down horizontally. 1 2 3 4 5 0 6 x Definition : Copyright © 2000 by Monica Yuskaitis Definition y axis – a vertical number line on a coordinate grid. 1 2 3 4 5 0 6 y Hint : Copyright © 2000 by Monica Yuskaitis Hint y is the tallest and stands upright or vertically. 1 2 3 4 5 0 6 y Definition : Copyright © 2000 by Monica Yuskaitis Definition Coordinates – an ordered pair of numbers that give the location of a point on a grid. (3, 4) 1 2 3 4 5 0 6 1 2 3 4 5 0 6 (3,4) Hint : Copyright © 2000 by Monica Yuskaitis Hint The first number is always the x or first letter in the alphabet. The second number is always the y the second letter in the alphabet. 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (3,4) How to Plot Ordered Pairs : Copyright © 2000 by Monica Yuskaitis How to Plot Ordered Pairs Step 1 – Always find the x value first, moving horizontally either right (positive) or left (negative). 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (2, 3) y x How to Plot Ordered Pairs : Copyright © 2000 by Monica Yuskaitis How to Plot Ordered Pairs Step 2 – Starting from your new position find the y value by moving vertically either up (positive) or down (negative). 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (2, 3) (2,3) y x How to Find Ordered Pairs : Copyright © 2000 by Monica Yuskaitis How to Find Ordered Pairs Step 1 – Find how far over horizontally the point is by counting to the right (positive) or the left (negative). 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (5, ) y x How to Find Ordered Pairs : Copyright © 2000 by Monica Yuskaitis How to Find Ordered Pairs Step 2 – Now count how far vertically the point is by counting up (positive) or down (negative). 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (5,4) y x What is the ordered pair? : Copyright © 2000 by Monica Yuskaitis What is the ordered pair? 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (3,5) y x What is the ordered pair? : Copyright © 2000 by Monica Yuskaitis What is the ordered pair? 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (2,6) y x What is the ordered pair? : Copyright © 2000 by Monica Yuskaitis What is the ordered pair? 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (4,0) y x What is the ordered pair? : Copyright © 2000 by Monica Yuskaitis What is the ordered pair? 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (0,5) y x What is the ordered pair? : Copyright © 2000 by Monica Yuskaitis What is the ordered pair? 1 3 2 4 5 0 6 1 2 3 4 5 0 6 (1,1) y x Four Quadrants of Coordinate Grid : Copyright © 2000 by Monica Yuskaitis Four Quadrants of Coordinate Grid When the number lines are extended into the negative number lines you add 3 more quadrants to the coordinate grid. -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 y x Four Quadrants of Coordinate Grid : Copyright © 2000 by Monica Yuskaitis Four Quadrants of Coordinate Grid If the x is negative you move to the left of the 0. -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 x = -2 y x Four Quadrants of Coordinate Grid : Copyright © 2000 by Monica Yuskaitis Four Quadrants of Coordinate Grid If the y is negative you move down below the zero. -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 y = -3 y x How to Plot in 4 Quadrants : Copyright © 2000 by Monica Yuskaitis How to Plot in 4 Quadrants Step 1 - Plot the x number first moving to the left when the number is negative. -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (-3, -2) y x How to Plot in 4 Quadrants : Copyright © 2000 by Monica Yuskaitis How to Plot in 4 Quadrants Step 2 - Plot the y number moving from your new position down 2 when the number is negative. -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (-3, -2) y x How to Plot in 4 Quadrants : Copyright © 2000 by Monica Yuskaitis How to Plot in 4 Quadrants When x is positive and y is negative, plot the ordered pair in this manner. -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (2, -2) y x How to Plot in 4 Quadrants : Copyright © 2000 by Monica Yuskaitis How to Plot in 4 Quadrants When x is negative and y is positive, plot the ordered pair in this manner. -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (-2, 2) y x Plot This Ordered Pair : Copyright © 2000 by Monica Yuskaitis Plot This Ordered Pair -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (-3, -3) y x Plot This Ordered Pair : Copyright © 2000 by Monica Yuskaitis Plot This Ordered Pair -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (-1, 2) y x Plot This Ordered Pair : Copyright © 2000 by Monica Yuskaitis Plot This Ordered Pair -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (1, -1) y x Plot This Ordered Pair : Copyright © 2000 by Monica Yuskaitis Plot This Ordered Pair -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (2, -2) y x Plot This Ordered Pair : Copyright © 2000 by Monica Yuskaitis Plot This Ordered Pair -2 0 -1 1 2 -3 3 -2 -1 0 1 2 -3 3 (-3, -2) y x Credits : Copyright © 2000 by Monica Yuskaitis Credits Clipart from “Microsoft Clip Gallery” located on the Internet at http://cgl.microsoft.com/ clipgallerylive/default.asp You do not have the permission to view this presentation.
