This all depends on how the problem is asked.
If we are asked the equation, and we want to determine the rate of change at the given point, differentiate the function (or take the derivative of the function) and substitute the dependent variable with the given value.
OR
If we are given two points with two known coordinates, then use the secant slope form, which states that:
m = (f(b) - f(a))/(b - a)
This is called the average rate of change.

How to find the constant rate of change?
To find the constant rate of change is by taking the final minus initial over the initial.
Why do take derivative?
To find rate of change. Two common examples are: rate of change in position = velocity and rate of change of velocity = acceleration.
What equation do you use to find the rate of change?
Rate of change = amount of change in some period of time/amount of time for the change
What is a sentence for unit rate?
the unit rate of this problem that we need to find our deals with 1
What is the every-day use of a derivative?
To find the rate of change. Velocity, for example, is the rate of change of distance - in a specified direction. Acceleration is the rate of change of velocity.
