so do the same as the first problem we had?
OpenStudy (anonymous):
You want the slope to stay the same the slop is 3x. So it has to be either c or d.
OpenStudy (anonymous):
then plug in x?
OpenStudy (sachintha):
Yeah same as before.
OpenStudy (anonymous):
its d

i didnt need the answer. i needed help with solving it
OpenStudy (anonymous):
@sourav_aich don't just give away answers try to help people learn how to do the math so they can learn it.
OpenStudy (sachintha):
First turn the equation to the form y= mx+c
OpenStudy (anonymous):
the 3x- y = -3?
OpenStudy (sachintha):
yeah.

how do i ove the 3x back?
OpenStudy (anonymous):
just sumbtract both sides?
OpenStudy (anonymous):
subtract*
OpenStudy (sachintha):
yeah and then divide the whole equation by -1 so you get positive y.
OpenStudy (anonymous):
y= 3x + 6

+3 sorry not 6
OpenStudy (anonymous):
so y= 3x +3
What do i do from here
OpenStudy (sachintha):
Continue as you did before.
OpenStudy (anonymous):
so just plug the rest in
y= 3x - 14
x=4
y= 12-14
y=-2
OpenStudy (anonymous):
so it i d
