To determine the slope of the line given the table of values, we can use the formula for slope (m):

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

  1. Let's take the first two points from the table: (-2, 1) and (2, 2).

    • Here, \( (x_1, y_1) = (-2, 1) \) and \( (x_2, y_2) = (2, 2) \).
  2. Now, plug these values into the slope formula:

\[ m = \frac{2 - 1}{2 - (-2)} = \frac{1}{2 + 2} = \frac{1}{4} \]

Alternatively, we can also check with the third point (10, 4):

Using the second point (2, 2) and the third point (10, 4):

\[ m = \frac{4 - 2}{10 - 2} = \frac{2}{8} = \frac{1}{4} \]

So, the slope of the line is \(\frac{1}{4}\).
