\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{6})~\hspace{10em} slope = m\implies -5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-6=-5[x-(-2)]\implies y-6=-5(x+2)


\bf y-6=-5x-10\implies y=-5x\stackrel{\downarrow }{-4}\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{y-intercept}{(0,-4)}~\hfill

The midpoint of JK is point L at (–1, 8). One endpoint is J(4, –15). Which equations can be solved to determine the coordinates
ycow [4]
Given two endpoints: (x_1,\ y_1) and (x_2,\ y_2), the midpoint of the two endpoints (x_m,\ y_m) is given by
(x_m,\ y_m)=\left( \frac{x_1+x_2}{2} ,\  \frac{y_1+y_2}{2}\right)

Thus, given the midpoint L(-1, 8) and one endpoint J(4, -15). The second endpont is given by
(-1,\ 8)=\left( \frac{x_1+4}{2} ,\ \frac{y_1+(-15)}{2}\right)
i.e.
\frac{x_1+4}{2} =-1 \\  \\ x_1+4=-2 \\  \\ x_1=-2-4=-6
and
\frac{y_1+(-15)}{2}=8 \\  \\ y_1-15=16 \\  \\ y_1=16+15=31
