Question

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

Answer 1

-1/9

Explanation:

plug in the slope formula:

y-y

-----

x-x

=9-8

-------

1-10

=-1/9

Answer 2

`-(1)/(9)`

Explanation:

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

The slope is equal to:
`(\Delta y)/(\Delta x) = (-1)/(9) = -(1)/(9)`
