How would you graph the inequality x > -5
If you are on a number line, draw an open small circle at x= -5, then a line to the right of -5 with an arrow on the line
If you graphing in the xy-plane, draw a dotted line at x = -5 and shade in the region to the right of that line
The region to the right of the x = -5 vertical line should be indicated as the solution region, by crosshatching, coloring or shading that region, or by blacking out the other region to the left of x=-5
See http://www.purplemath.com/modules/ineqgrph.htm for some ideas
