We want to find a graph that represents Noah's average speed.
We define the average speed as the quotient between the distance moved and the time it takes to move that distance, then in this case we will have:
s = 12ft/6s = 2ft/s
Then we can define a linear equation:
y = (2ft/s)*x
As the distance that Noah travels in x seconds.
The graph of the given linear function can be seen below, and that is the graph with the slope that best represents Noah's average speed.

Step-by-step explanation:

First, let's move all of the terms with an
to the left-hand side of t he equation, and everything else to the right-hand side of the equation.


Next, let's divide both sides by
to isolate the
variable by itself on the left-hand side of the equation:


F(-4)=11...because x is less than 3, you use the top one.
