Question 278379
We need to convert to the form (r, theta).

(1) Graph the given point on the xy-plane.

(2) From the graph we can see that the radius is the distance from the origin to the point (0, -3).  So, the radius is 3.

(3) We ow need to find theta.

If we begin to rotate from the positive measure on the x-axis to the given point (0,-3), we will end our rotation on the y-axis below the x-axis where the value of theta is 270 degrees.

So, (0,-3) can be written as (3, 270) in polar form.
