120-45-5. = $70 profit for each quilt
Monthly total expenses are $5,200
5200/ 70=74.28
So you need to sell at least 75 quilts to break even
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.
x+3y=9
-x -x
----------
3y=9-x
Then, rewrite it as:
3y=-x+9
_______
3 3
simplify to
y=-x/3 +9
