# What is the slope of the line passing through the following points:  (1, 3), (-3,9)?

slope $m = - \frac{3}{2}$

#### Explanation:

Given -

${x}_{1} = 1$
${y}_{1} = 3$
${x}_{2} = - 3$
${y}_{2} = 9$

Slope $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}} = \frac{9 - 3}{- 3 - 1} = \frac{6}{- 4} = - \frac{3}{2}$
