Finding the rate of change - in particular, the instantaneous rate of change.
rate = distance / time (r= d/t)
The rate, or rate of change is like an average all except it has to do with the slope of a line instead of a group of numbers. Finding the rate of change is like finding an average except you use the points on the graph instead of numbers in a group.
The calculus operation for finding the rate of change in an equation is differentiation. By taking the derivative of the equation, you can find the rate at which one variable changes with respect to another.
You need a book, not an answer here for that question.

Perimeters = sum of sides added together
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
