3. Match the equation with its graph. –6/7x – 1/2y = 3/7

OpenStudy (coconutjj):

graph?

OpenStudy (zuha):

hold on

OpenStudy (coconutjj):

Change equation into y intercept form(y=mx+b)

OpenStudy (zuha):

Graph one

OpenStudy (zuha):

Graph 2

OpenStudy (zuha):

Graph 3

OpenStudy (zuha):

Graph 4

OpenStudy (zuha):

cant do 2 of them , have to have only one.

OpenStudy (coconutjj):

??? It cannot be graph 2 or graph 3

OpenStudy (zuha):

how did you calculate ?

OpenStudy (coconutjj):

change into y=mx+b form

OpenStudy (zuha):

oh ok let me see

OpenStudy (coconutjj):

\[y=\frac{ -12 }{ 7 }x-\frac{ 6 }{ 7 }\]

OpenStudy (zuha):

i think its the last graph
