The total volume is 45. I got this answer by adding all of it together
Answer: y = x - 1
<u>Step-by-step explanation:</u>
Use the Point-Slope form: y - y₁ = m(x - x₁) where
- (x₁ , y₁) is any point on the line
- m is the slope of the line

Let (x₁, y₁) = (2, 1) and (x₂, y₂) = (-4, -5)

Point-Slope form: y - 1 = 1(x - 2)
y - 1 = x - 2 <em>distributed 1 to (x - 2)</em>
y = x - 1 <em>added 1 to both sides</em>
The one on the left is -5/6
The one on the right is 1/21
