$\huge\text{Hey there!}$

$\rm{f(x) = \dfrac{1}{2}x + 4}\\\\\\\rm{f(x)= \dfrac{1}{2}(8) + 4}\\\\\\\rm{y = \dfrac{1}{2}(8) + 4}\\\\\\\rm{\dfrac{1}{2}(8)\rightarrow \dfrac{1}{2}\times8=\boxed{\bf 4}}\\\\\\\rm{y = \bold{4} + 4}\\\\\\\rm{y = \boxed{\bf 8}}\\\\\\\\\huge\boxed{\rm{Therefore, your\ answer\ is: y = \bf 8}}\huge\checkmark$
