We need to find thr rate of change (slope) of the line joining these two points ~
[tex]\qquad \sf \dashrightarrow \: m = \dfrac{rise}{run} [/tex]
[tex]\qquad \sf \dashrightarrow \: m = \cfrac{8 - ( - 8)}{0 - ( - 8)} [/tex]
[tex]\qquad \sf \dashrightarrow \: m = \cfrac{8 + 8}{0 + 8} [/tex]
[tex]\qquad \sf \dashrightarrow \: m = \cfrac{16}{8} [/tex]
[tex]\qquad \sf \dashrightarrow \: m = 2[/tex]
Slope of the line (m) joining the two points is 2 ~
