Writing a Function Rule

This video shows how functions typically behave, and how they can be written out. Functions usually have a variable with a coefficient in front that represents the rate of change, and have a constant value that represents the starting point of the function.
The setup for this would look like:

Where # represents a constant
 y = (\#) x + (\#)
( (#x)  \rightarrow This is the starting point, x = 0 )
( (#)  \rightarrow This is the constant change )
