Answer:

9/2

Step-by-step explanation:

It is the ratio between y-values for consecutive x-values. Perhaps the easiest two points to work with are ...

Crazy boy [7]

Check the picture below

thus

$\bf r^2=x^2+y^2\impliedby \textit{now, "y" is a constant, thus }\implies r^2=x^2+64
\\\\\\
2r\cfrac{dr}{dt}=2x\cfrac{dx}{dt}+0\implies \cfrac{dr}{dt}=\cfrac{x\frac{dx}{dt}}{r}\quad 
\begin{cases}
x=6\\
\frac{dx}{dt}=3\\
r=\sqrt{x^2+y^2}\\
\qquad \sqrt{6^2+64}\\
\qquad 10
\end{cases}
\\\\\\
\cfrac{dr}{dt}=\cfrac{6\cdot 3}{10}$
