1. The Coordinate Plane

2. We have worked with both horizontal and vertical number line s Horizontal -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5 +6 +7 +8 +9 +10 Vertical (thermometer)

3. When a vertical number line and a horizontal number line intersect at right angles and at the point zero on each line, they form ___________ on a ________________ -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5 +6 +7 +8 +9 +10 The number lines intersect at the _______________ We label the _________ axis with ______ We label the _______ axis with _____ y x axes coordinate plane origin horizontal x vertical y

4. The axes divide the coordinate plane into four sections called ________________ +1 +2 +3 +4 +5 +6 -2 -3-4-5 -6 +1 +2 +3 +4 -2 -3 -4 -5 +5 +7-7 x y Quadrant 1Quadrant 2 Quadrant 3 Quadrant 4

5. +1 +2 +3 +4 +5 +6 -2 -3-4-5 -6 +1 +2 +3 +4 -2 -3 -4 -5 +5 +7-7 x y Plot each point on the coordinate plane. Then describe its location. a) A (5, 1)b) B (-3,-5)c) C (3, -2) d) D (-4, 2)e) E (2, -2)f) F (0,0) 0

6. +1 +2 +3 +4 +5 +6 -2 -3-4-5 -6 +1 +2 +3 +4 -2 -3 -4 -5 +5 +7-7 x y K J L M P N 0 Write the ordered pair for each point.

7. +1 +2 +3 +4 +5 +6 -2 -3-4-5 -6 +1 +2 +3 +4 -2 -3 -4 -5 +5 +7-7 x y 0 Plot each set of points and join them in order to form a quadrilateral. Identify each quadrilateral. 1) A (1, 1), B (1, 5), C(-3, 5), D(-3, 1) 2) J (1, -3), K (5, 1), L(2, 1), M(4, -3)
