What would be the correct graph of the solution to the inequality -13 > -5 + 2 > -28

Is there an "X" in the problem somewhere?  You have -13 > -5 + 2 > -28.
 
If the x is by the -5, then we have -13 > -5x + 2 > -28
Like regular algebra:  subtract two from both sides
 
-13 - 2 > -5x + 2 - 2 > -28 - 2
-15 > -5x > -30
 
Now, divided by -5 (REMEMBER WHEN YOU DIVIDED BY NEGATIVE, THE > SIGN CHANGES TO <)
 
3 < X < 6
 
Correct graph would be a unfilled circle on the x = 3 line and would be a solid line to the number x = 6.  at the X = 6, there would be another unfilled circle (meaning NOT EQUAL TO).
