Create a table of values by assinging values to $x$ then solving for the corresponding value of $y$ for each $x$: \begin{array}{ccc} &x &y &(x, y)\\ &0 &0 &(0, 0)\\ &1 &1 &(1,1)\\ &-1 &-1 &(-1,-1)\\ &2 &2 &(2,2)\\ &-2 &-2 &(-2,-2)\\ \end{array} Plot the points then connect them using a line. Refer to the graph above.
