# What is the slope of the line passing through the following points:  (25,17) ; (18,8)?

$m = \frac{9}{7}$

#### Explanation:

Given -

${x}_{1} = 25$
${y}_{1} = 17$
${x}_{2} = 18$
${y}_{2} = 8$

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}} = \frac{8 - 17}{18 - 25} = \frac{- 9}{- 7} = \frac{9}{7}$
