Find the slope of the line that passes through the points (0, -3) and (-4,1).

kozerog [31]

The formula for slope is $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

In this case:

$y_{2} = 1\\ y_{1} }= -3\\x_{2} = -4\\x_{1} = 0$

so...

$\frac{1 - (-3)}{-4 - 0}$

$\frac{4}{-4}$

-1 <<<The slope

Hope this helped!
