To find the missing value in the point-slope form of the linear equation, we first need to identify the slope of the line defined by the points given.
The points provided are: (-2, 8), (-1, 5), (0, 2), (1, -1), (2, -4).
Let's calculate the slope (m) using two points from the data. We can use points (-1, 5) and (0, 2):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{0 - (-1)} = \frac{-3}{1} = -3. \]
Now, we can use the slope of -3 and one of the points to write the point-slope form of the equation. The point-slope form is given by:
\[ y - y_1 = m(x - x_1). \]
Using the point (1, -1) (which is one of the points given), we substitute \(y_1 = -1\), \(m = -3\), and \(x_1 = 1\):
\[ y - (-1) = -3(x - 1). \]
This simplifies to:
\[ y + 1 = -3(x - 1). \]
Now, rearranging to match the point-slope form:
Thus, in the point-slope form \(y - __ = -3(x - 1)\), the missing value is:
\(-1\).
So, the final answer is:
-1.
