Question

Find the slope of the line that passes through (10,8) and (1,9).

Answer 1

Answer:

$-\frac{1}{9}$

Step-by-step explanation:

between (1, 9) and (10, 8), the x moves by 9 and y moves by -1

The slope is equal to: $\frac{\Delta y}{\Delta x} = \frac{-1}{9} = -\frac{1}{9}$

Answer 2

Answer:

-1/9

Step-by-step explanation:

plug in the slope formula:

y-y

-----

x-x

=9-8

-------

1-10

=-1/9
