D--because it has y^2 in the equation and to isolate y you have to take the square root, the graph is going to be curved rather than linear.
Answer:
Hello,
I believe that your answer is A. (250,100)
Hope this helps
100. This is very easy thanks teacher
First solve for the trig function 'cot'

Next take the sqrt of both sides (include plus/minus)

Now take reciprocal of both sides, this will change trig function to 'tan'
(cot = 1/tan)

Finally use the unit circle or inverse tan on your calculator to find x.
There will be 4 solutions, one for each quadrant.
