1. P7 The Cartesian Plane

2. Quick review of graphing, axes, quadrants, origin, point plotting

3. Distance Formula : derived from Pythagorean Theorem

4. Examples Find the distance between (-2,1) and (3, 4) Show that (2, 1), (4, 0), and (5, 7) are vertices of a right triangle.

5. Midpoint Formula: Example Find the midpoint of (-5, -3) and (9, 3)

6. 1.1 Graphs of Equations Sketch these two graphs

7. Intercepts of the Graph X-intercept:where it crosses the x-axis Y-intercept:where it crosses the y-axis

8. Find the x & y intercepts

9. Symmetry x axis: (x.y) and (x, -y) y axis: even function (x, y) and (-x, y) Origin: odd function (x, y) and (-x, -y)

10. Testing for Symmetry

11. Use intercepts and symmetry to sketch the graph.
