We need to find thr rate of change (slope) of the line joining these two points ~


\qquad \sf  \dashrightarrow \: m = (rise)/(run)


\qquad \sf  \dashrightarrow \: m = \cfrac{8 - ( - 8)}{0 - ( - 8)}


\qquad \sf  \dashrightarrow \: m = \cfrac{8 + 8}{0 + 8}


\qquad \sf  \dashrightarrow \: m = \cfrac{16}{8}


\qquad \sf  \dashrightarrow \: m = 2

Slope of the line (m) joining the two points is 2 ~
