What is a limit?

When trying to understand limits, It is easiest to think of some kind of function (curve or line) on an x and y graph. Let's pretend we are looking at a simple upward slopping line. The line can represent how far you are from your home relative to time. If the line is upward slopping, this means that as time passes, you are getting farther and farther away from your home. In this case, we are looking at the relationship between time (x axis) and distance (y axis). Finding the limit of this function would mean finding the relationship that y has to x or in this case, how quickly you are moving away from your house. Are you running or strolling?
