"e thing" above is supposed to be "theta"

and theta=-2 is a polar equation

θ = -2

This is just a straight line, along the angle θ=-2.

Recall that the slope of the line: tanθ = sinθ/cosθ = rsinθ/rcosθ = y/x

So, y/x = tan(-2) = 2.185

y = 2.185x

Makes sense, since θ is in QIII, so the line slopes up from the left.
