The graph third represents the polar equation rsinθ = -2 and the rectangular form of the polar equation is y = -2.
What is the polar equation?
A polar coordinate system is a two-dimensional coordinate system in which a distance from a reference point and an angle from a reference direction identify each point on a plane.
We have a polar equation:
rsinθ = -2
As we know, to convert a rectangular equation to polar, we must plug:
x = rcosθ
y = rsinθ
And r =√(x²+y²)
Replace rsinθ with y in the polar equation.
y = -2 (it is horizontal line)
Thus, the graph third represents the polar equation rsinθ = -2 and the rectangular form of the polar equation is y = -2.
