To solve the problem, we are asked to find the coordinates of point \( P \), where line \( L \) is parallel to the line given by \( y = 4x + 3 \).

### Key Information:
- The equation of the given line is \( y = 4x + 3 \). This is in slope-intercept form \( y = mx + b \), where the slope \( m = 4 \) and the y-intercept \( b = 3 \).
- Line \( L \) is parallel to this line, which means it will have the same slope, \( m = 4 \), but a different y-intercept.
- From the graph, line \( L \) passes through the point \( (0, -3) \) (as marked in the image). This means we can use this point to find the equation of line \( L \).

### Step 1: Find the Equation of Line \( L \)
Since line \( L \) has the same slope as the line \( y = 4x + 3 \), its equation will also be in the form \( y = 4x + b \). We can use the point \( (0, -3) \), which lies on line \( L \), to find the value of \( b \).

Substitute \( x = 0 \) and \( y = -3 \) into the equation:
\[
-3 = 4(0) + b
\]
\[
b = -3
\]
So, the equation of line \( L \) is:
\[
y = 4x - 3
\]

### Step 2: Find the Coordinates of Point \( P \)
Point \( P \) is the intersection of line \( L \) and the vertical line \( x = 1 \) (as shown in the graph). To find the y-coordinate of point \( P \), substitute \( x = 1 \) into the equation of line \( L \).

\[
y = 4(1) - 3
\]
\[
y = 4 - 3 = 1
\]

Thus, the coordinates of point \( P \) are \( (1, 1) \).

### Final Answer:
The coordinates of point \( P \) are \( \mathbf{(1, 1)} \).
