Answer:
y=-6/5+9
Step-by-step explanation:
your going ro put it in y=mx+b format
so it would be ur equation 12x+10y=90
subtract 12x from both sides and get 10y=-12x+90
u have to get 10 by itself so you divide 10 to everything and get y=-12/10x+90/10
you have to simplify so get y=-6/5+9
Answer:
the graph shift down 135 units
Step-by-step explanation:
when there is no fixing cost:
f(x)=12x-1400
when there is fixing cost (0ne time): 12x-(1400+135)
the graph shift down 135 units
