Systems of Equations- Graphing November 28, 2011
OBJECTIVE: SWBAT SOLVE SYSTEMS BY GRAPHING, ELIMINATION AND SUBSTITUTION
Today we learned about the three different types of systems of equations. The three methods are graphing, elimination and substitution. When graphing, always convert equations to y=mx+b. When you graph both lines, look for the point of intersection. This point is your solution set. A solution set is a solution to the equations that you graphed; it must satisfy both. Parallel lines have no solution; they have a solution, but they don’t share the same solution. You graphing your lines you should start labeling them. An example is shown below.
