-18.2 + 3.6= -14.6 is the answer to the question
I'm pretty sure it's Identity I hope it helps :)
The solution can be found where two lines intersect. The lines in the image do not intersect at an exact point, so we will need to estimate.
The x value is either 1 or -1 from your choices. You can see it is closer to -1 on the horizontal (x axis).
The y value is either 0 or -1 from your choices. You can see it is closer to 0 on the vertical (y axis).
The answer to your set of lines is approximately (-1,0).
So the total is 120. You want 1/6 of those.
So do (1/6)*120
You get 20.
