Well, in the plane x=rcosθ and y=rsinθ. So 4x+3y=2 becomes

4rcosθ+3rsinθ=2, or r=2/(4cosθ+3sinθ). That's all!

r = 4 / (a million - cos ?) bypass multiply r(a million - cos ?) = 4 r - r cos ? = 4 replace r with ?(x^2 + y^2) and r cos ? = x ?(x^2 + y^2) - x = 4 ?(x^2 + y^2) = 4 + x squaring x^2 + y^2 = sixteen + x^2 + 8x y^2 = 8(x + 2) x + 2 = (a million/8)y^2 it quite is eqn of parabola
