i believe it is -10
OpenStudy (shelby1290):
so for x+2y=7 it would be when you have the x-int, y=0 and when you have the y-int, x=0 ..right?
OpenStudy (shelby1290):
i got the same answer as you
OpenStudy (shelby1290):
x-int y=0
x+2(0)=7
x=7
y-int x=0
(0)+2y=7
2y/2 = 7/2
y=7/2
OpenStudy (shelby1290):

wait so x+2y=8
changes to..
3+2(2)=8
OpenStudy (shelby1290):
oops sorry i was looking at it wrong
OpenStudy (shelby1290):
so 3+2(2)=7
OpenStudy (shelby1290):
