A polar graph
Select the correct answer below:


A
B
C
D

Answer 1

The correct answer is b!

Answer 2

Answer: Correct answer is B

Explanation:

Remember that the coordinates (−1,π4) tell us the radius r=−1 and the angle θ=π4. So the point should be on the circle labeled 1 and form an angle of π4 with the negative x-axis. Point B is the correct point.
