See solution below.

Note that for any value of $x$ you choose, the equation $y=-3$ tells you that you have a $y$ -value of $-3$ . In table form, you get the following

${:(ul(x),ul(y)),(-2,-3),(-1,-3),(color(white)(a)0,-3),(color(white)(a)1,-3),(color(white)(a)2,-3),(color(white)(a)3,-3):}$

When we plug these values into a graph we get the following

Next step is to simply connect the dots with a straight line, like so:
