(r,θ)=(−3,−π2) will be a point on the positive Y-axis, 3 units above the origin.
(see below)

Explanation:

A graph showing the point (r,θ)=(−3,−π2)
and (hopefully) indicating it's derivation:

The angle of −π2 is measured clockwise (since it is negative) from the X-axis.
A radius of −3 is measured along the radial arm in the opposite direction (since it is negative) from the normal direction of the radial arm.
