Answer:

See solution below.

Explanation:

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
