convert è = -2 to rectangular equation form

"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.
