Answer 1

To find the slope of the line that passes through the points \((10, 8)\) and \((1, 9)\), you can use the slope formula:

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

Where:
- \((x_1, y_1) = (10, 8)\)
- \((x_2, y_2) = (1, 9)\)

Now substituting the values into the formula:

\[
m = \frac{9 - 8}{1 - 10} = \frac{1}{-9} = -\frac{1}{9}
\]

Thus, the slope of the line is:

\[
\text{Slope} = -\frac{1}{9}
\]
