@.Mehek.

OpenStudy (volleyballlover55):

??

OpenStudy (.mehek.):

OpenStudy (volleyballlover55):

-12,-8

OpenStudy (.mehek.):

\(\dfrac{-4--8}{-4--12}=?\)

OpenStudy (volleyballlover55):

-12 / -16

OpenStudy (.mehek.):

No

OpenStudy (volleyballlover55):

oh sorry, 4/8

OpenStudy (.mehek.):

which is simplified to 1/2 Choose two other ordered pairs

OpenStudy (volleyballlover55):

ok... 0,-2 -8,-6

OpenStudy (.mehek.):

We do the same thing \(\dfrac{-6--2}{-8-0}=?\)

OpenStudy (volleyballlover55):

-4/-8

OpenStudy (.mehek.):

which is also simplified to 1/2

OpenStudy (volleyballlover55):

ok..

OpenStudy (.mehek.):

That means it is linear

OpenStudy (volleyballlover55):

ok so what would be the answer?

OpenStudy (.mehek.):
