hey green how do u graph them

igreen · Answer

Just copy and paste them in a box on the left.

anonymous · Answer

n then when I do what should happen

igreen · Answer

Then you have to plot the points too..

igreen · Answer

Just copy and paste them.

igreen · Answer

Then it'll show the two lines, where the two lines OVERLAP is where the solutions are. So you want to see the solutions that are in the OVERLAP.

Sometimes they end up on the lines that make up the overlap. If the point is on a line that's DOTTED than it is NOT a solution. But if it's on a SOLID line than it IS a solution.
