To find the slope and y-intercept, the equation needs to be in the form $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. Rearranging $x + 2y = 1$ gives $2y = -x + 1$, and then $y = -\frac{1}{2}x + \frac{1}{2}$. Therefore, the slope is $-\frac{1}{2}$ and the y-intercept is $\frac{1}{2}$.
