Answer:
b>-5
Step-by-step explanation:

Multiply by 5 to isolate b.

If you graph this on a line, it would be a hollow point facing the right, since it's any number greater than five, not including 5.
If you put any number greater than -5, you'll output greater than - 1.
4x-3=9x-13
10=5x
2=x
So these functions intersect when x=2.
