How do you write constraints in slope-intercept form?

Question

anonymous · Answer

y>mx+b or y<mx+b

anonymous · Answer

I know that I mean how do I get the slope-intercept form from the constraint?

anonymous · Answer

could also be y>=mx+b or y<=mx+b

anonymous · Answer

these are in slope intercept form

anonymous · Answer

{4x + 3y ≥ 30
{ x + 3y ≥ 21
{ x ≥ 0, y ≥ 0
Minimum for 
C = 5x + 8y

How do I make that into slope-intercept form? That's what I'm trying to figure out

anonymous · Answer

well i would say for example C=5x-8y add 8y to both sides 8y+c=5x subtract c by both sides 8y=5x-c divide both sides by 8 to get y=(5/8)x-(1/8)c

wait no scrach that read the question wrong

anonymous · Answer

not too sure about this but i would say try plugging the top equations to find the answer with the smallest slope
