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.
