Can anyone help me with this? I've been trying to figure it out but no luck. Where do I plot the points and how do I sketch the graph?

All help is greatly appreciated!

Your link is bad, at least for me. Any chance you could type out the problem using $\LaTeX$? Or could you scan a page in and post it?
