How do you write the equation in point slope form given (3,0), m= -2?

$y = - 2 \left(x - 3\right)$

Explanation:

The equation of a line in $\textcolor{b l u e}{\text{point-slope form}}$ is.

$\textcolor{red}{\overline{\underline{| \textcolor{w h i t e}{\frac{2}{2}} \textcolor{b l a c k}{y - {y}_{1} = m \left(x - {x}_{1}\right)} \textcolor{w h i t e}{\frac{2}{2}} |}}}$
where m represents the slope and $\left({x}_{1} , {y}_{1}\right) \text{ a point on the line}$

$\text{here "m=-2" and } \left({x}_{1} , {y}_{1}\right) = \left(3 , 0\right)$

$\Rightarrow y - 0 = - 2 \left(x - 3\right)$

$\Rightarrow y = - 2 \left(x - 3\right) \leftarrow \textcolor{red}{\text{ in point-slope form}}$
