Problem
Find the coordinates of the \( y \)-intercept for the given equation. \[ x+2 y=1 \] \( (2,0) \) \( (2,2) \) \( (0,2) \) \( \left(0, \frac{1}{2}\right) \)
Solution
Step 1 ：Set \(x=0\) to find \(y\)-intercept.
Step 2 ：Substitute \(0\) for \(x\) in the equation: \(0+2y=1\).
Step 3 ：Solve for \(y\): \(y=\frac{1}{2}\)
