Sagot :

To find the slope of the line that passes through the points [tex]\((7, -9)\)[/tex] and [tex]\((6, -11)\)[/tex], we use the formula for the slope between two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex]:

[tex]\[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]

### Step-by-Step Solution:

1. Identify the coordinates of the two points:

[tex]\[ (x_1, y_1) = (7, -9) \][/tex]
[tex]\[ (x_2, y_2) = (6, -11) \][/tex]

2. Calculate the difference in the y-coordinates ([tex]\( \Delta y \)[/tex]):

[tex]\[ \Delta y = y_2 - y_1 = -11 - (-9) = -11 + 9 = -2 \][/tex]

3. Calculate the difference in the x-coordinates ([tex]\( \Delta x \)[/tex]):

[tex]\[ \Delta x = x_2 - x_1 = 6 - 7 = -1 \][/tex]

4. Substitute these differences into the slope formula:

[tex]\[ \text{slope} = \frac{\Delta y}{\Delta x} = \frac{-2}{-1} = 2 \][/tex]

### Final Answer:

The slope of the line that passes through the points [tex]\((7, -9)\)[/tex] and [tex]\((6, -11)\)[/tex] is:

[tex]\[ \boxed{2} \][/tex]
