To find the slope of a line, you can use any two points from the given table and apply the slope formula:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Let's use the points $(1, -7)$ and $(3, -2)$ from the table. Applying the formula:

$m = \frac{-2 - (-7)}{3 - 1} = \frac{-2 + 7}{2} = \frac{5}{2}$

Thus, the slope of the line is $\frac{5}{2}$.

Here are 5 related questions:

1. What is the slope-intercept form of the equation of this line?
2. Can we use any two points to find the slope of a line?
3. How do we interpret the slope in practical terms?
4. How would the slope change if one point is incorrect?
5. How do we find the equation of a line if we know the slope and a point?

Tip: When choosing points to find the slope, make sure the points are distinct and correctly substituted into the formula.
