Hi Dana;
I wish I could draw a graph for you.  I will do the best I can.
x ≥ -3
I do not know if you are familiar with the signs, > and <.  When I was in the sixth grade, the way we remembered this is, The alligator is going to eat the bigger one.
In this circumstance, the alligator will eat anything which is equal to or greater than x as -3.  On a graph, create a vertical line of x=-3 corresponding to all y=coordinates, and shade the area to the right.
You have to shadow half of coordinate plane on the right from the vertical solid line passing through x = - 3 and is parallel to the y-axis. The shadowed area will be the solution of the given inequality.
The graph is all of the plane on and to the right of the vertical line whose equation is x=-3.  Take two points whose x-coordinates are -3, say (-3,-3), and (-3,3),  connect with a straight line.
