Math Blog post Week 11

This week in math, we learned how to graph inequalities and systems of equations. This week, we combined our last 2 units and made it into one (Solving Quadratics, and Graphing inequalities and systems). We learned that if the equal sign has a line on the bottom which means equal that it will have a solid line when graphing. $slatex y\le4x+5$. Knowing this we can add a point to check which part to shade in, in this case i used (-2,1)

-2>4(1)+5 =      -2> 8+5

This shows us that we need to shade the bottom side of the graph, because the test points for this solution was not true.
