David asks…

Find the average rate of change of the function from x1 to x2?

I need help to find the average rate of change of this function:
f(x)= -2/3x+5 and x1= -5, x2= 3
Please help!!!! I don’t understand this at all!!!! Please show me step by step how to do it if you can! Thanks so much!!!
If you could figure out this one, can you figure out this one?
f(x)=1- square root(x+3)
x1=1 and x2=6

Administrator answers:

F(x) = – 2/3 x + 5

The average rate of change and the slope of a linear function are the same. The slope of this function is the coefficient of the x-term, or – 2/3.
