y equals 4x+1 is a parallel line to y equals 4x.
4x = y : or it can be written in the reverse order, y = 4x.

y equals 4x+1 is a parallel line to y equals 4x.
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
4x = y : or it can be written in the reverse order, y = 4x.

8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0
y = 4x-3
y=4
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
Parallel. They both have a slope of 4.
y equals 2
