$\text{slope: } -9 ,\\\text{a point on the line: } (7,-1)$

Using $y-y_1=m(x-x_1)$ or the Point-Slope form where $m$ is the slope and $(x_1,y_1)$ is a point on the line, then the given equation, $ y+1=-9(x-7) $, has the following characteristics: \begin{array}{l} \text{slope: } -9 ,\\\text{a point on the line: } (7,-1) .\end{array}
