1. COORDINATE POINTS & COORDINATE PLANE

2. MATH VOCABULARY Coordinate plane Formed by two intersecting lines (named X and Y) Origin The middle/center of the coordinate, also known as (0, 0) [the START point when graphing] Axis The intersecting lines that form a coordinate plane Ordered pair A given point based on a specific “coordinate” by order of x and y Quadrant Sections of the graph

3. COORDINATE PLANE When graphing points… *always recognize Quadrant *graph left  right on x-axis THEN up/down [following] y-axis (alphabetical order!! x before y)

4. COORDINATE PLANE Four sections: Quadrant I *upper right of graph *points (+x, +y) Ex. (3, 5)

5. COORDINATE PLANE Four sections: Quadrant II *upper left of graph *points (-x, +y) Ex. (-2, 4)

6. COORDINATE PLANE Four sections: Quadrant III *lower left of graph *points (-x, -y) Ex. (-5, -2)

7. COORDINATE PLANE Four sections: Quadrant IV *lower right of graph *points (+x, -y) Ex. (3, -1)

8. PRACTICE Graph AND label: a)(-2, 1) b)(4, 3) c)(-5, -4) d)(2, -4) e)(0, -5) f)(3, 0)
