0606.3.9 Graph ordered pairs of integers in all four quadrants of the Cartesian coordinate system. I CAN graph ordered pairs in ALL four quadrants!!! Have you ever had to give directions or follow someone else's direction to get to a specific destination? http://www.findlatitudeandlongitude.com/ We use a coordinate system on earth to find exact locations. The equator is like the x-axis, and the prime meridian is like the y-axis. The lines that run eastwest are lines of latitude. They are measured in degrees north and south of the equator. The lines that run northsouth are lines of longitude. They are measured in degrees east and west of the prime meridian. y-axis x-axis origin coordinate plane - is formed by two number lines in a plane that intersect at right angles. The point of intersection is the zero on each number line. x-axis - horizontal axis y-axis - vertical axis Quadrants - the two axes divide the coordinate plane into four sections Origin - the point where the axes intersect Coordinates - the numbers in an ordered pair y-axis Quadrant II (-, +) Quadrant I (+, +) Origin (0, 0) Quadrant III (-, -) Quadrant IV (+, -) x-axis Have you ever used a ladder? First you have to move the ladder towards what you want to clime Second, you climb up Or used an elevator? First you have to go over and into the elevator Then you go up or down A (-2, 3) B (1, 2) C (0, -2) D (-2, -3) 1. Which location in Texas is closest to the ordered pair (5, 2)? Galveston 2. Which location in Texas is closest to the ordered pair (6, 1)? El Paso 3. What ordered pair best describes the location of Dallas, Texas? (3, 2) 4. Which place in Texas is located in Quadrant III of this coordinate plane? Big Bend National Park Texas Graph the following coordinates. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. A (-4, 3) B (-8, 3) C (-8, 0) D (-4, 0) E (-4, -3) F (-8, -3) G (2, 3) H (-2, 3) I (-2, -3) J (2, -3) K (4, -3) L (4, 3) M (6, 0) N (8, 3) O (8, -3) My Example Rough draft of your picture. Rough draft picture approved by the teacher. After teacher approval put dots/points where they belong and label them for capital letters. Write your letters on the side of the paper in order, including stops. Write the ordered pair and the matching letter. 2nd sheet of graph paper - plot your points and connect. List ordered pairs (coordinates) on a separate piece of paper. This will be exchanged with other students. On Monday you will turn in rough draft, final picture, and ordered pairs (coordinates). Turn to your shoulder partner and explain how the graphing project meets the objective for today!!!!
