Plot each point given its polar coordinates. Then, give another pair of polar coordinates for the same point with the opposite radius and angle 0 ≤ 0 < 2π (or 0 ≤ 0 < 360°). (-6, 120°)

Identify which quadrants in the polar coordinate system the following points lie.  1. (5,9π/7) 2. (-5, 6π/7) 3. (-5,3π/7) 4. (5,-4π/7)

For the point (-2,- 135°) in polar coordinates, (a) plot the point, (b) give two other pairs of polar coordinates for the point, and (c) give the rectangular coordinates for the point. a) Choose the correct graph below. O A. OB. 90° OC. 90° OD. 180° 90° 180° 90° 180° 270° 180° 270° 0. 270° 270°
