The table provides several points on the graph of the linear function \( k(x) \). The points given are:

- \( (-3, -130) \)
- \( (2, 0) \)
- \( (5, 78) \)
- \( (11, 234) \)

To determine which function represents \( k(x) \), we need to calculate the slope and find the equation of the line using the points provided.

### Step 1: Find the slope of the line
We can use the slope formula:

\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

Let's use the points \( (2, 0) \) and \( (5, 78) \):

\[
m = \frac{78 - 0}{5 - 2} = \frac{78}{3} = 26
\]

So the slope \( m = 26 \).

### Step 2: Find the equation of the line
Using the slope-point form of the equation of a line, \( y - y_1 = m(x - x_1) \), and the point \( (2, 0) \):

\[
y - 0 = 26(x - 2)
\]

\[
k(x) = 26(x - 2)
\]

This matches option **D**.

Thus, the correct function is:

\[
\boxed{D. \, k(x) = 26(x - 2)}
\]

2. How would the equation change if the slope was negative?
3. What is the significance of the slope in a linear equation?
4. How can you find the y-intercept from the equation of a line?
5. Can you rewrite the equation in slope-intercept form?

**Tip**: In a linear equation, the slope indicates how much \( y \) changes for each unit change in \( x \).
