This week, I have learned how to graph inequalities. It is very similar to graph linear graph; however, the difference is that you color.
Let’s see this example. It has the same line as linear graphing, however, we can see that there is a shaded area. It is shaded because it proves the equation that all of the shaded part is correct.
The equation is : y<2x-8
We can use 0,0 to see if this equation makes sense.
If it doesn’t we don’t shade in that side.
If it does work, we shade it in.
Since 0<-8 doesn’t make sense, we didn’t shade it in.
As a result, it is very simple to do inequality graphing. Its very simple and similar but difference between the shading.
