Answer:
A) At x = 4 and y = 2
Step-by-step explanation:
When you have something like (4,2), as shown above, the first number in parenthesis is x while the second number is y.
So here, the 4 would be x and the y would be 2
I think the answer is A but I am not sure. I think you would take the opposite of the y axis.
16 - (-15) = 16 + 15 = 31...difference of 31 degrees
