x+4y(greater than or equal to)8
&
2x-y>4
I don't really need the graph as much as I need help finding the answer..
What am I suppose to do?
Please help, it's been too long for me to remember.

bless your questions :)
basically ignore the inequality sign for now and call it =.
so x+4y=8
2x-y=4
to plot the graph youve got to find some coordinates and its bst to use zero and then extend the line. youll see what i mean once its done. so zero is the best.
say x was = to 0 in equation one, so 0 +4y = 8. therefore the y coordinate here is 2, yes?
so (0,2) is our first coordinate ( mark on graph )
say if y = 0 then x+4(0)=8 so x = 8
i hope you see what were doing here.
so the other coordinates would be (8,0).
you can choose any x value but its easier to do it this way. try another value to find x or y and youll see itll be on your graph.
hence now connect the lines and it should be a straight line
<= means above the region
=> means below the region
