# How do you find the slope of (0,0); (-2,7) without a graph?

Jul 19, 2018

The slope is $- \frac{7}{2}$ or $- 3.5$.

#### Explanation:

To find the slope given two points without using a graph, we use the formula $\text{rise"/"run}$, or $\frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$.

Plug in the given points into the formula:
$\frac{7 - 0}{- 2 - 0} = \frac{7}{-} 2 = - \frac{7}{2}$

Therefore, the slope is $- \frac{7}{2}$ or $- 3.5$.

Hope this helps!
