Complete the point slope equation of the line through (-8,-8) & ' (-7,9) y-9=
Answers: 1
![\bf \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ % (a,b) &&(~ -8 &,& -8~) % (c,d) &&(~ -7 &,& 9~) \end{array} \\\\\\ % slope = m slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{9-(-8)}{-7-(-8)}\implies \cfrac{9+8}{-7+8} \\\\\\ \cfrac{17}{1}\implies 17 \\\\\\ % point-slope intercept \stackrel{\textit{point-slope form}}{y- y_2= m(x- x_2)}\implies y-9=17[x-(-7)] \\\\\\ y-9=17(x+7)](/tpl/images/0125/8053/50738.png)
