The equation in standard form would be,

All you have to do is move -2/7x to the other side.
Hope this helped

Answer:
3,872.32
Step-by-step explanation:
the nearest hundredth is 2 numbers on the right of the decimal sign. So you round up from 5 to get answer above.
For part B
the fixed cost is 500 dollars because it is a set inital amount, the varibale cost is .15 because it is the cost dependent on something else (per indicated variable part)
y=.15x+500
.15 cents per flyer, add 500 because that is the set amount it costs to even create the flyer
Plug in 500 for the equation
y=.15(500)+500
y=75+500
y=575
for part a
b=ka for direct variations so the direct one is C - two items directly multiplied
y=mx+b for partial variation so its A,D - basically the equation of a line
A is neither - shows neither of these relationships
