Answer:
The answer is
[tex] - \frac{1}{9} [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(10, 8) and (1, 9)
The slope is
[tex]m = \frac{9 - 8}{1 - 10} = \frac{1}{ - 9} \\ = - \frac{1}{9} [/tex]
We have the final answer as
[tex] - \frac{1}{9} \\ [/tex]
Hope this helps you
