On the graph of the equation 3x - 2y = -18, what is the value of the y-intercept? Answer -9 -6 6 9

OpenStudy (anonymous):

bring it to form : y=ax+b

OpenStudy (anonymous):

then b will be the y intercept

Parth (parthkohli):

Set \(\rm x\) to 0 and find \(\rm y\).

OpenStudy (anonymous):

or as @parthkholi said :)

OpenStudy (anonymous):

hmmm

OpenStudy (anonymous):

replacing x by 0 is easier .. what do you get if you do so ?

OpenStudy (anonymous):

3(0) - 2y = -18

Parth (parthkohli):

Yes, and that makes\[\rm -2y = -18\]

OpenStudy (anonymous):

so.. what is y ?

OpenStudy (anonymous):

One moment please

OpenStudy (anonymous):

9

OpenStudy (anonymous):

correct

OpenStudy (anonymous):

Thank you
