# How do you write the point slope form of an equation for a lint that passes through (9,-5) with m=0?

See a solution process below:

#### 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 $\left(\textcolor{red}{{x}_{1} , {y}_{1}}\right)$ is a point the line passes through.

Substituting the slope and values from the point in the problem gives:

$\left(y - \textcolor{red}{- 5}\right) = \textcolor{b l u e}{0} \left(x - \textcolor{red}{9}\right)$

$\left(y + \textcolor{red}{5}\right) = \textcolor{b l u e}{0} \left(x - \textcolor{red}{9}\right)$
