WEEK 10 – MATH 11 – GRAPHING INEQUALITYS

In this week we learned how to graph an inequality.
Say we have 2x + 3y > 6

First, we must make the Y a 0
2x > 6
Then we must divide both sides by 2
x > 3
Then change the > to a =
x = 3
we then repeat the same steps for the Y axis to end up with
y = 2

Once you have these two points plot both on the grid and connect them. after this follow the line to reach each side of your graph.

Next, we must figure out which side is true. to do this we must replace the 2x + 3y with a 0 so we end up with
0 > 6
Now we ask our self, is 0 greater than 6?
since its no, the shaded side will be the side without 0 on it.
