similar problem @ http://openstudy.com/users/ganeshie8#/updates/522617bde4b06211a67febfe see if it helps :)

anonymous · Answer

@ganeshie8 i just need help figuring out what i did wrong, I graphed the inequalities but it doesn't form a polygon

dumbcow · Answer

is this same one i help with before?

anonymous · Answer

@dumbcow yes i thought i understood once you explained the process, but then once I graphed them they didn't form a polygon

dumbcow · Answer

looks like you may have not graphed the lines correctly...make sure you solve for "y" and get it in "y=mx+b" form

anonymous · Answer

i did that.. the three equations in y=mx+b form that i got were y is greater than or equal to x +8, y is less than or equal to 1/3x +4, and y is greater than or equal to x-2

dumbcow · Answer

the first line should be
$$y \ge -x+8$$

dumbcow · Answer

the other 2 are correct :)

anonymous · Answer

ohhh okay i see what i did
