Assuming you've fulfilled all of these requirements, and can back that up with a portfolio of work, test scores, etc., you have graduated. That doesn't necessarily mean, however, that you have fulfilled all the requirements for the college you want to get into - you should call admissions and find out if you need more units of math, science, etc. depending on your major. What the college wants is usually going to be more than what the state requires.
EDIT: Never mind, I see you're going to community college. So you need to put together sufficient portfolio / test scores to show that you have in fact completed those 26.5 credits, with an overview showing how they apply to graduation requirements for Missouri.
