To find the value of \( y^\circ \) in the image, let's analyze the given information.

The diagram shows a straight line with an angle labeled \( 140^\circ \) on one side and an angle labeled \( y^\circ \) on the other side. These angles form a linear pair.

### Step-by-Step Solution:
1. **Linear Pair Property**: The angles on a straight line add up to \( 180^\circ \).
   
   \[
   y^\circ + 140^\circ = 180^\circ
   \]

2. **Solve for \( y \)**:
   \[
   y^\circ = 180^\circ - 140^\circ = 40^\circ
   \]

### Final Answer:
The value of \( y^\circ \) is \( 40^\circ \).
