The line 4√3 x - 4y = 1 has slope √3

So, we want y'=√3

4y^3 y' = 2yy' - 2x

y' = -2x/(4y^3 - 2y)

y' = x/(y - 2y^3)

x/(y - 2y^3) = √3

x = √3(y - 2y^3)

√(y^2 - y^4) = √3(y-2y^3)

y^2 - y^4 = 3(y^2 - 4y^4 + 4y^6)

12y^6 - 11y^4 + 2y^2 = 0

y^2 = 2/3 or 1/4

x^2 = 2/9 or 3/64

If you graph it, you will see that at the points

(.47,.50) and (-.22,.81) the tangent is parallel to the given line.
