# How do you write the point slope form of the equation given (1,-3) and slope 0?

Feb 14, 2017

The formula in point-slope form is: $\left(y + \textcolor{red}{3}\right) = \textcolor{b l u e}{0} \left(x - \textcolor{red}{1}\right)$

#### 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 problem gives:

$\left(y - \textcolor{red}{- 3}\right) = \textcolor{b l u e}{0} \left(x - \textcolor{red}{1}\right)$

$\left(y + \textcolor{red}{3}\right) = \textcolor{b l u e}{0} \left(x - \textcolor{red}{1}\right)$
