Remember the initial value of the function is the output when the input is zero, so in the equation f(x)=b+mx, the graph includes the point (0, b).

From a graph of a line, this tells us that if we divide the vertical difference, or rise, of the function outputs by the horizontal difference, or run, of the inputs, we will obtain the rate of change, also called slope of the line.
