Question

Which of the points below correctly plots the point (2,7π/4)?

Points are plotted on a polar graph.

Answer 1

Answer: E is correct

Explanation:

Remember that the coordinates (2,7π4) tell us the radius r=2 and the angle θ=7π4. So the point should be on the circle labeled 2 and form an angle of 7π4 with the positive x-axis. Point E is the correct point.
