Answer: <em>2x + y = 10</em>
Step-by-step explanation: When we're given a point and a slope, we can use the point-slope formula to write the equation of a line.
The point-slope formula is y - y₁ = m(x - x₁).
Now we can substitute our point and our slope into the formula.
y - 4 = -2(x - 3)
~distribute
y - 4 = -2x + 6
~isolate y
y = -2x + 10
~put into standard form
2x + y = 10

Option A, $65,280
Step-by-step explanation:
The volume of the tank is,
12×20×15+40×(50-15)×12
= 3600+16800
=20400 cubic meters
For each cubic meter, it costs $3.20, so for 20400 cubic meters it'll cost,
20400×$3.20
= $65,280
