# How do you find the slope of the line that contains the points, (1, 2) and (2, 5)?

$\text{difference in y-coordinates"/"difference between corresponding x-coordinates}$
For two points $\left(\textcolor{red}{1} , \textcolor{b l u e}{2}\right)$ and $\left(\textcolor{red}{2} , \textcolor{b l u e}{5}\right)$
$m = \frac{\Delta y}{\Delta x} = \frac{\textcolor{b l u e}{5 - 2}}{\textcolor{red}{2 - 1}} = 3$
