I am really confused!!!
how do you make a table for solutions? For example y=2x The table of solutions shows 0,0; 1,2; 1,2;2,4;2,4 The would than be plotted on a graph. What I can't figure out is how they got the pairs.

You plug in one value as 'x' to find 'y'. or vice versa.
ex. y=2x
I will use 1 for x
2*1=2 so, y=2
WHen you plot this on a graph you plot it as (1,2). 1 being on the xaxis, and 2 on the yaxis.
