What is the rate of change between (-8,- 8) and (0,8)

Sagot :

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 ~
