To find the reflection of the line \( f(x) = \frac{5}{4}x - 2 \) and understand the type of reflection involved, we need to consider how reflections work in the coordinate plane.
1. **Reflection over the y-axis**: When a function \( f(x) \) is reflected over the y-axis, the new function \( g(x) \) will be \( g(x) = f(-x) \). This changes the sign of the \( x \) term.
2. **Reflection over the x-axis**: When a function \( f(x) \) is reflected over the x-axis, the new function \( g(x) \) will be \( g(x) = -f(x) \). This changes the sign of the entire function.
### Step 1: Find the reflection over the y-axis
Starting with:
\[ f(x) = \frac{5}{4}x - 2 \]
Reflect over the y-axis:
\[ g(x) = f(-x) = \frac{5}{4}(-x) - 2 = -\frac{5}{4}x - 2 \]
### Step 2: Find the reflection over the x-axis
Using the same original function:
\[ f(x) = \frac{5}{4}x - 2 \]
Reflect over the x-axis:
\[ g(x) = -f(x) = -\left(\frac{5}{4}x - 2\right) = -\frac{5}{4}x + 2 \]
### Step 3: Analyze the given options
From the steps above:
- The reflection over the **y-axis** gives \( g(x) = -\frac{5}{4}x - 2 \).
- The reflection over the **x-axis** gives \( g(x) = -\frac{5}{4}x + 2 \).
Now let's consider the options given:
1. The Reflection is over the **y-axis** such that \( g(x) = -\frac{4}{5}x + 2 \). The rule for the Reflection is \( r_{y-axis} \).
2. The Reflection is over the **y-axis** such that \( g(x) = -\frac{5}{4}x + 2 \). The rule for the Reflection is \( r_{yaxis} \).
3. The Reflection is over the **x-axis** such that \( g(x) = -\frac{5}{4}x + 2 \). The rule for the Reflection is \( r_{x axis} \).
4. The Reflection is over the **x-axis** such that \( g(x) = -\frac{4}{5}x + 2 \). The rule for the Reflection is \( r_{x axis} \).
The correct reflection is:
- Over the **x-axis** with \( g(x) = -\frac{5}{4}x + 2 \) which follows the rule \( r_{x axis} \).
Thus, the correct choice is:
**The Reflection is over the x axis such that \( g(x) = -\frac{5}{4}x + 2 \). The rule for the Reflection is \( r_{x axis} \).**

3. The Reflection is over the **x-axis** such that \( g(x) = -\frac{5}{4}x + 2 \). The rule for the Reflection is \( r_{x axis} \).
4. The Reflection is over the **x-axis** such that \( g(x) = -\frac{4}{5}x + 2 \). The rule for the Reflection is \( r_{x axis} \).
The correct reflection is:
- Over the **x-axis** with \( g(x) = -\frac{5}{4}x + 2 \) which follows the rule \( r_{x axis} \).
Thus, the correct choice is:
**The Reflection is over the x axis such that \( g(x) = -\frac{5}{4}x + 2 \). The rule for the Reflection is \( r_{x axis} \).**

Let me clarify and ensure accuracy regarding the reflection of the line \( f(x) = \frac{5}{4}x - 2 \).
### Original Function
The equation of the line with a positive slope is:
\[ f(x) = \frac{5}{4}x - 2 \]
### Reflection Types
1. **Reflection Over the y-axis**:
- For any function \( f(x) \), reflecting it over the y-axis results in \( g(x) = f(-x) \).
So we compute:
\[
g(x) = f(-x) = \frac{5}{4}(-x) - 2 = -\frac{5}{4}x - 2
\]
2. **Reflection Over the x-axis**:
- For reflection over the x-axis, we take the negative of the entire function, resulting in:
\[
g(x) = -f(x) = -\left(\frac{5}{4}x - 2\right) = -\frac{5}{4}x + 2
\]
### Analyzing Your Choices
From my calculations:
- Over the y-axis, the reflection results in \( g(x) = -\frac{5}{4}x - 2 \).
- Over the x-axis, the reflection results in \( g(x) = -\frac{5}{4}x + 2 \).
Now let's review your options again:
1. **Over the y-axis such that** \( g(x) = -\frac{4}{5}x + 2 \) (incorrect)
2. **Over the y-axis such that** \( g(x) = -\frac{5}{4}x + 2 \) (incorrect)
3. **Over the x-axis such that** \( g(x) = -\frac{5}{4}x + 2 \) (correct)
4. **Over the x-axis such that** \( g(x) = -\frac{4}{5}x + 2 \) (incorrect)
The accurate answer regarding the reflection of the given line \( f(x) \) reflects over the **x-axis** resulting in:
\[ g(x) = -\frac{5}{4}x + 2 \]
### Conclusion
Thus, I confirm that the correct answer is:
**The Reflection is over the x-axis such that \( g(x) = -\frac{5}{4}x + 2 \). The rule for the Reflection is \( r_{x-axis} \).** Thank you for your patience, and I appreciate your diligence in verifying this!
