###### Definition4.6.4Point-Slope Form

When \(x\) and \(y\) have a linear relationship where \(m\) is the slope and \((x_0,y_0)\) is some specific point that the line passes through, one equation for this relationship is

\begin{equation}
y=m\left(x-x_0\right)+y_0\tag{4.6.1}
\end{equation}

and this equation is called the point-slope form of the line. It is called this because the slope and one point on the line are immediately discernible from the numbers in the equation.
