Here are some tips:
 A completed picture has been provided to be used as a key.
 Using a ruler helps to align each line with its equation.
 You can download my custom made FREE GRAPH PAPER from my store.
 I have also found that printing graph paper directly from themathworksheetsite.com
helps out, but any graph paper will do.
 Remember to copy double-sided to save paper.
 Technology Option: Use your favorite equation and domain graphing software or website. I prefer desmos.com
