# What is the slope of the line passing through  (-3,-3); (0,0)?

Apr 19, 2018

The slope is $1$. See explanation.

#### Explanation:

When 2 points on a line A=(x_1;y_1) and B=(x_2;y_2) are given then the slope of the line passing through the points can be calculated as:

## $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

Here we have:

$m = \frac{0 - \left(- 3\right)}{0 - \left(- 3\right)} = \frac{0 + 3}{0 + 3} = \frac{3}{3} = 1$
