To compare the rate of change of Linear Function 1 with Linear Function 2, we first need to identify the slope (rate of change) for each function.

### Linear Function 1:
The equation is given as:
\[ y = 15x + 8 \]
In this equation, the coefficient of \( x \) (which is 15) represents the slope. Therefore, the rate of change for Linear Function 1 is **15**.

### Linear Function 2:
For Linear Function 2, we can determine the slope using the two points provided: (5, 26) and (13, 34).

The formula for the slope \( m \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]

Substituting the points into the formula:
- Let \((x_1, y_1) = (5, 26)\)
- Let \((x_2, y_2) = (13, 34)\)

Now calculate the slope:
\[
m = \frac{34 - 26}{13 - 5} = \frac{8}{8} = 1
\]

### Summary of Rates of Change:
- **Linear Function 1** has a rate of change (slope) of **15**.
- **Linear Function 2** has a rate of change (slope) of **1**.

### Conclusion:
Linear Function 1 has a greater rate of change than Linear Function 2, as 15 is greater than 1.

Yes, let's go over the calculations again step by step to ensure accuracy.

### Linear Function 1:
The equation is given as:
\[ y = 15x + 8 \]

In this equation:
- The slope (rate of change) is the coefficient of \( x \), which is **15**.

### Linear Function 2:
The points provided are:
- Point 1: (5, 26)
- Point 2: (13, 34)

To find the slope (rate of change), we'll use the slope formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]

Substituting the values:
- \( y_1 = 26 \), \( y_2 = 34 \)
- \( x_1 = 5 \), \( x_2 = 13 \)

Now plug in the values:
\[
m = \frac{34 - 26}{13 - 5} = \frac{8}{8} = 1
\]

### Summary:
- **Linear Function 1** has a slope of **15**.
- **Linear Function 2** has a slope of **1**.

### Conclusion:
Linear Function 1 does indeed have a greater rate of change (slope of 15) compared to Linear Function 2 (slope of 1). I confirm that the comparison is accurate. Thank you for your patience!
