Well we can see very clearly that our change in x over this interval is equal to positive two. Well what's our change in y over the same interval? Our change in y is equal to, when x went increased by two from one to three, y increases by eight. So it's gonna be a positive eight. So what is our average rate of change? Well it's gonna be our change in y over our change in x, which is equal to eight over two, which is equal to four. So that would be our average rate of change.
