    Re: rate of change

    Solution :

    Given The rate of change is represented in this formula;
    y= 3.63+1.22x
    this is in 2 year
    then in 1 year = (3.63+1.22x)/2
    the annual rate of change=1.815+0.61x

    What exactly do you mean by this? That y is changing in this way? Or that y gives the rate of change of some other quantity?

    However this is over a period of 2 years
    And what do you mean by this? The rate of change "over a period of two years" does not tell us anything about what the rate of change of any shorter (or longer) period might be.

    What is the annual rate of change?
