Express the proportionality as an equation with a constant of variation, $y^2 = k(x+b)$. Use the two given sets of values for x and y to form a system of two equations, and solve for the unknown constant 'b'.
If $y^2 \propto (x+b)$ and $y = 6$ when $x = 13$, $y = 9$ when $x = 46\frac{3}{4}$, what is the value of b?
