Which of the following could be the equation of a line parallel to the line y=-4x+1

Answer 1

y=-4x + b where b is any number other than 1.

any parallel has the same slope = -4, the coefficient of the x term when the equation is solved for y. b, the y intercept, can be any number, except 1. If b were 1, then it wouldn't be "parallel," it would be the identical same line.
