The slope of the line  that passes through (10,8)
and (9, 13) is – 5
Solution:
Given, two points are (10, 8) and (9, 13) Â
We have to find the slope of a line that passes through the above given two points.
Slope of a line that pass through
is given as:
![\mathrm{m}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](/tpl/images/0364/0015/dcfc9.png)
![\text { Here, in our problem, } x_{1}=10, y_{1}=8 \text { and } x_{2}=9, y_{2}=13](/tpl/images/0364/0015/33580.png)
![\text { slope } m=\frac{13-8}{9-10}=\frac{5}{-1}](/tpl/images/0364/0015/a17a5.png)
![=\frac{-5}{1}=-5](/tpl/images/0364/0015/d3e7d.png)
Hence, the slope the line that passes through the given points is – 5
