To determine the slope of the linear function represented by the table, we need to use the slope formula:

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

We can select any two points from the table. Let's use the points $(x_1, y_1) = (-2, -2)$ and $(x_2, y_2) = (-1, 1)$:

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

Thus, the slope of the linear function is 3.

Here are five related questions you might find useful:

1. How would the slope change if the function were decreasing?
2. What is the significance of the slope in a real-world context?
3. How do you calculate the y-intercept from this table?
4. Can the slope be determined from any pair of points on the line?
5. What does a slope of zero represent for a function?

Tip: When finding the slope from a table, you can choose any two points, as the slope will be the same for all pairs of points in a linear function.
