Aim: How do we find a common solution to more difficult system of linear equations?

Test Notice
Test # 8 will be administered on Friday, Dec. 22. 2006

The test will include the following topics:

1. Finding the slope of a line from two orderd pairs
2. Indentifying the slope and y-intercept from an equation.
3. Find the the slope from the graph of a line
4. Writing an equation from the grapn
5. Write an equation of a line given two points.
6. Write an equation of a line given one point and a slope.
7. What is the relationship of the slope and lines that are parallel?
8. What is the realtionship of the slope and lines that are perpendicular?
9. What is the solution of a system of equations having one common point?
