Find the slope of the line that passes through (10, 8) and (1, 9)?
sdas [7]

Answer:

The answer is

<h2>-  \frac{1}{9}</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(10, 8) and (1, 9)

The slope is

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

We have the final answer as

-  \frac{1}{9}  \\

Hope this helps you
