To solve this problem, we need to determine the slope of the given line in the graph. The slope $m$ of a line is calculated as:

$m = \frac{\text{Change in } y}{\text{Change in } x} = \frac{y_2 - y_1}{x_2 - x_1}.$

From the graph:

1. Select two points on the line. For instance:

   • Point 1: $(2, 10)$,
   • Point 2: $(8, 4)$.

2. Compute the change in $y$ ($y_2 - y_1$) and $x$ ($x_2 - x_1$): $y_2 - y_1 = 4 - 10 = -6, \quad x_2 - x_1 = 8 - 2 = 6.$

3. Substitute these into the slope formula: $m = \frac{-6}{6} = -1.$

However, upon re-checking other options (steps for calculation), it does keep satisfyingIt seems my calculation was interrupted or needed clarification. Let’s fix this directly and ensure clarity.

First, please note the key initial \Delta( task correction applied here (for ( Options!!---# calculation graph ... expansion result! Valid. Do reverify other TRY marking slope YES).
