To find the slope of the line represented by the table of values, we can use the formula for the slope \( m \):
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
We can use any two points from the table. Let's take the points \((-7, 9)\) and \((3, -7)\).
Here, \( (x_1, y_1) = (-7, 9) \) and \( (x_2, y_2) = (3, -7) \).
Now plug the values into the slope formula:
\[
m = \frac{-7 - 9}{3 - (-7)}
\]
Calculating the numerator:
\[
-7 - 9 = -16
\]
Calculating the denominator:
\[
3 - (-7) = 3 + 7 = 10
\]
Now substituting these values into the slope formula:
\[
m = \frac{-16}{10} = \frac{-8}{5}
\]
Thus, the slope of the line is \( \frac{-8}{5} \).
**The correct response is: \( -\frac{8}{5} \)**.
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
