You need to graph it so I guess
She worked 4+3+6 hours = 13 hoursso 13x+10 = 120.50
13x=110.50
x=8.5
so she makes $8.50 an hour which is A.
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!

12 because triangles will always have an odd number, and 12 is even
I think
