What is the average rate of change from x=1 to x=4

Hello from MrBillDoesMath!

-1 (which is the second choice)

Discussion:

Average rate of change = ( f(b) - f(a))  / (b-a)  .

For us,  a = 1 and b = 4. f(1) = 3 (from the graph) and  f(4) = 0. Hence

average rate of change =  

(0 - 3)/(4-1) =

-3/3 =

-1

The second choice.

Thank you,

MrB

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
