Find the equation of the line, which is parallel to y-axis at a distance of `2` units to the right of it.

Answer

To find the equation of a line that is parallel to the y-axis and located 2 units to the right of it, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Position of the Line**:
- A line that is parallel to the y-axis will have the same x-coordinate for all points on that line.
- Since we need the line to be 2 units to the right of the y-axis, we can visualize that the y-axis is at x = 0.

**Hint**: Remember that lines parallel to the y-axis have a constant x-value.

2. **Determine the x-coordinate**:
- The line is 2 units to the right of the y-axis, which means the x-coordinate of our line will be 2.

**Hint**: The distance to the right of the y-axis is positive, so we add 2 to the x-coordinate of the y-axis.

3. **Formulate the Equation**:
- Since the line is vertical and parallel to the y-axis, the equation of the line can be expressed in the form \( x = a \), where \( a \) is the x-coordinate we determined.
- Therefore, the equation of the line is \( x = 2 \).

**Hint**: Vertical lines are represented by equations of the form \( x = \text{constant} \).

### Final Answer:
The equation of the line that is parallel to the y-axis and 2 units to the right of it is:
\[ x = 2 \]
