Answer
The correct options are D and E.
D. The slopes are the same but, the \( y \)-intercepts are different.
E. The systems of equations create no solution.
Solution
Let's analyze the given system of equations:
\[
\begin{cases}
y = 2x + 4 \\
y = 2x + 1
\end{cases}
\]
1. **Slope Comparison**:
- Both equations have the same slope (\( m = 2 \)).
2. **Y-Intercept Comparison**:
- The first equation has a y-intercept of \( 4 \).
- The second equation has a y-intercept of \( 1 \).
Since both lines have the **same slope** but **different y-intercepts**, they are **parallel** and will **never intersect**. This means:
- There is **no solution** to the system because there is no point \((x, y)\) that satisfies both equations simultaneously.
**Evaluating the Options:**
- **A. The systems of equations create one solution.**
- **Incorrect**. Parallel lines do not intersect, so there is no solution.
- **B. The slopes are different but, the \( y \)-intercepts are the same.**
- **Incorrect**. The slopes are the **same**, and the y-intercepts are **different**.
- **C. The systems of equations create infinitely many solutions.**
- **Incorrect**. This would only be true if both equations were identical.
- **D. The slopes are the same but, the \( y \)-intercepts are different.**
- **Correct**. This accurately describes the given system.
- **E. The systems of equations create no solution.**
- **Correct**. Parallel lines do not intersect, resulting in no solution.
**Therefore, the correct options are D and E.**
**Answer:**
D. The slopes are the same but, the \( y \)-intercepts are different.
E. The systems of equations create no solution.

Bonus Knowledge
The slopes of both equations are the same: \(2\). However, their \(y\)-intercepts differ; one intercepts the y-axis at \(4\) while the other at \(1\). This indicates that they are parallel lines, which means they will never intersect. Thus, the two correct answers are: D. The slopes are the same but, the \(y\)-intercepts are different. E. The systems of equations create no solution.
