Answer:
<em>Assuming person A and person B are part of the 7 people</em>, there are 10 ways the 7 people can line up if A needs to be first or last and B needs to be in the middle.
Step-by-step explanation:
There are 2 places for A (first, last) and 5 places for B (anywhere but first or last). 2 x 5 = 10.
Look at the coordinates. They are both negative. (-5,-1)
Let me plot all the coordinates so you can see:
Joe= (-3,4)
Dan= (1,4)
Roy= (2,-3)
Lee= (-3,-4)
The only person with coordinates that are both negative is Lee.
"C" is the answer. Lee.
I hope this helps!
