A. I think I’m not all the way sure
I think it is Y equals -1/3x +4.6
I guess it is simplifying the expression:

Answer:
y = 4x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 4x - y = 1 into this form
add y to both sides
4x = y + 1 ( subtract 1 from both sides )
4x - 1 = y
y = 4x - 1 ← in slope-intercept form
Scale factor for volume = A^3:B^3
(1:4)^3 = 1:64. The volume is 64x bigger.
