# How do you write the point slope form of the equation given m=-1 and (-6,12)?

Jan 26, 2017

$\left(y - \textcolor{red}{12}\right) = \textcolor{b l u e}{- 1} \left(x + \textcolor{red}{6}\right)$

#### Explanation:

The point-slope formula states: $\left(y - \textcolor{red}{{y}_{1}}\right) = \textcolor{b l u e}{m} \left(x - \textcolor{red}{{x}_{1}}\right)$

Where $\textcolor{b l u e}{m}$ is the slope and $\textcolor{red}{\left(\left({x}_{1} , {y}_{1}\right)\right)}$ is a point the line passes through.

Substituting the values from the information given in the problem gives:

$\left(y - \textcolor{red}{12}\right) = \textcolor{b l u e}{- 1} \left(x - \textcolor{red}{- 6}\right)$

$\left(y - \textcolor{red}{12}\right) = \textcolor{b l u e}{- 1} \left(x + \textcolor{red}{6}\right)$
