Today in on adventure in Mathland, we took a little trip to Systemetropolis! We learned how to graph systems of inequalities. Graphing them can be quite extensive at times, but if you follow these rock solid steps, and you'll never be overwhelmed.
1. Replace the inequality sign, and sketch graph of resulting equation.
2. Test one point in each of the regions formed by the graph in step 1. If the point satisfies the inequality, shade the entire region to denote that every point in the region satisfies the inequality.
3. A solution of a system of inequalities in X and Y is a point (x,y) that satisfies the inequality in the system.
4. For a system of inequalities it is helpful to find the vertices of the solution region.
My adventure today was a blast! Graphing is fun! I can't wait until I get to go back to Mathland tomorrow!
