The table below represents the distance a person runs as a function of time:

The average rate of change of the function between x = 10 to x = 16 is __________ m/s and represents the person's speed.

Think it's 6 but just want to make sure.

ganeshie8 · Answer

average rate of change =  (change in y)/(change in x)
                                    = (96 - 60) / (16 - 10)
                                    =  36/6
                                    = 6

what is the slope of the line segment AB?
my answer is 2

other answers are 
-2
-1/2
1/2

ganeshie8 · Answer

i would say thats also a very good guess, but no
(really no this time)

meilendurcer · Answer

ok good. i'm thinking 1/2?

meilendurcer · Answer

the slope isn't in the negative side so it has to be 1/2

ganeshie8 · Answer

notice that the line is falling
if u sit on that line, u wil slide down to the right side...

ganeshie8 · Answer

so it must have a negative slope

ganeshie8 · Answer

falling line = negative slope
rising line = positive slope

meilendurcer · Answer

ah ok

meilendurcer · Answer

-1/2?

meilendurcer · Answer

thanks i would've failed that.

ganeshie8 · Answer

Exactly ! since it is falling down for just 1 unit after going right for 2 units
the slope is $-1/2$

ganeshie8 · Answer

good work !
