# What is the slope of the line passing through  (2,5); (-2,7)?

Jan 14, 2016

The slope is $- 0.5$ or $- \frac{1}{2}$

#### Explanation:

The slope formula is $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

So,
${y}_{2}$ = 7
${y}_{1}$ = 5

${x}_{2}$ = -2
${x}_{1}$ = 2

Replacing....

$m = \frac{7 - 5}{- 2 - 2}$
