you don't need to take the natural logarithm of both sides of the equation. Try to solve the derivative of f(x) using the chain rule first

notice that the square root of b^3 * x^2 * y is the same as (b^3 * x^2 * y)^0.5 that will let you use more logarithm identities to get numbers outside the logarithm

you're confusing the slope with the y value. y0 is the y-value of the point, m is the slope, and at (4,1/2) the slope m=-1/16
