please help

Integers are whole numbers. And you have a 4/5, so you'll need to multiply everything by 5 to get rid of the fraction.
OpenStudy (dtan5457):
y=4/5x+8
5y=4x+40
Now get that in standard form which is
ax+by=c
OpenStudy (dtan5457):
Got it from here?
OpenStudy (anonymous):
im confused because you said ax+by=c but you put 5y=4x+40 I don't understand

In standard form of ax+by=c
All it really means is to move x and y to one side and leave the whole number on the other.
5y=4x+40 is NOT in standard form yet
OpenStudy (anonymous):
oh ok
OpenStudy (anonymous):
so 4x+5y=40 is correct
OpenStudy (dtan5457):
Why is the 4x positive?
OpenStudy (anonymous):
its suppose to be positive

5y=4x+40
If you subtract the 4x on both sides
I don't see why it's positive
OpenStudy (anonymous):
4x + 5y = 40
OpenStudy (anonymous):
I mean -4x+5y=40
OpenStudy (dtan5457):
I'm going with 5y-4x=40
OpenStudy (dtan5457):
Yours work too, same thing.
