The function we have is:
This is a linear function.
We can find the slope (the rate of change) of this function, by comparing it to the general slope-intercept equation:
Where m is the slope (rate of change) and b is the y-intercept of the line.
By comparison, we see that m an b are:
Since we are asked for the value of the rate of change, the answer is the value of m:
which is option A.
