To find the fourth \( y \) value of the equation \( a_n = 5 + (n - 1) \cdot 2 \), we need to substitute \( n = 4 \) into the equation.

\[
a_n = 5 + (n - 1) \cdot 2
\]

Substituting \( n = 4 \):

\[
a_4 = 5 + (4 - 1) \cdot 2
\]
\[
a_4 = 5 + 3 \cdot 2
\]
\[
a_4 = 5 + 6
\]
\[
a_4 = 11
\]

Therefore, the fourth \( y \) value is \( 11 \).
