# What is the slope of the line passing through the following points:  (12,9), (5,1)?

Slope $m = \frac{8}{7}$

#### Explanation:

Given -

${x}_{1} = 12$
${y}_{1} = 9$
${x}_{2} = 5$
${y}_{2} = 1$

Slope $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}} = \frac{1 - 9}{5 - 12} = \frac{- 8}{- 7} = \frac{8}{7}$
