Question 86702: When there is only 2 I have no trouble but when 3 or more is added I get all messed up.
Solve each of the following systems of linear inequalities graphically.

3x-y<=6
x>=1
y<=3

You can put this solution on YOUR website!
----Step#1: Graph 3x-y<=6
Rewrite to y>=3x-6
+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+3x-6%29+
Since Y is equal-to-or-greater-than 3x-6, put "hash" marks to above that line
----Step#2: Graph x>=1 on the same graph
You should add a vertical line at X=1, and "hash" everything to the right of that line
(the software on this sight can't plot X=1, so I can't show you)
----Step#3: Graph y<=3 on the same graph
+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+3x-6%2C+3%29+
Since Y is equal-to-or-less-than 3, put "hash" marks to below that line

---------Solution: The area containing all "hash" marks from all 3 lines is the region bounded by the equations.....it should look like an upside-down triangle
