Answer:
A. 
Step-by-step explanation:
The given equation is
We solve for y by subtracting 3x from both sides to obtain;
We now divide through by -7 to get;
This simplifies to;
This equation is now in the form y=mx +c, where 
is the slope.
SimplifyingY + -9 = 4(x + -2)
Reorder the terms:-9 + Y = 4(x + -2)
Reorder the terms:-9 + Y = 4(-2 + x)-9 + Y = (-2 * 4 + x * 4)-9 + Y = (-8 + 4x)
Solving-9 + Y = -8 + 4x
Solving for variable 'Y'.
Move all terms containing Y to the left, all other terms to the right.
Add '9' to each side of the equation.-9 + 9 + Y = -8 + 9 + 4x
Combine like terms: -9 + 9 = 00 + Y = -8 + 9 + 4xY = -8 + 9 + 4x
Combine like terms: -8 + 9 = 1Y = 1 + 4x
SimplifyingY = 1 + 4x
1 hour = $8.00
48 hours = $8 x 48
48 hours = $384
