Ah hah ! NOW I see it. Thanks to BellBell for a good link.
My first impression is a dog bone standing up on one end.
You're talking about the area of the figure, so I'll think that over
before I look at the choices.
I see:
-- 2 semi-circles = 1 whole circle.
and
-- (1 rectangle) minus (a trapezoid).
Now I'll look through the choices.
A). No good. The trapezoid is cut OUT of the figure,
and shouldn't be added into it.
B). Oh ! Yes ! I didn't look at it that way at first, but
I can see how that works. 'B' is good.
C). and D). Yes. This was my description above.
So 'A' is the method that's wrong.
Answer:
The slope is 3.
Step-by-step explanation:
Let's use the slope formula to calculate the slope of this function. Remember, slope equals rise over run, or the difference between y coordinates divided by the difference between x coordinates of 2 points on the graph.
Let's use the last 2 points in the table: (1, 7) and (2, 10)

= 
= 
The slope of this function is 3!
Hope this helps :) Feel free to ask me any questions!
