Identify the polar coordinates given: (r, θ) = (6, -\frac{11\pi}{6}).
Understand that in polar coordinates, 'r' is the radial distance from the origin, and 'θ' is the angle measured from the positive x-axis.
Since the angle is negative, -\frac{11\pi}{6}, convert it to a positive angle by adding 2\pi. This gives us \frac{\pi}{6}.
Locate the angle \frac{\pi}{6} on the polar coordinate system, which is in the first quadrant.
From the origin, move along the line at angle \frac{\pi}{6} to a distance of 6 units to plot the point.
