What are the uses of the graph of the equation y = mx + b? What is the use of the knowledge when you learn the amount of unit changes in y because of one unit change in x?

Solution Preview

The equation y = mx + b can be used to "predict" or "forecast" the value of y for any given value of x. Moreover, the value

of m in the equation gives the magnitude of change in the value of y due to a unit change in the value of x. This

information is very useful ...
