Two lines are parallel. The equation of the first line is y = - 3x + 5. Which of the following cannot be the equation of the second line?

a. y = - 3x + 2

b. x - 3y = - 3

c. 3x + y = - 6

d. 6x + 2y = 2

For the equation to be equal it should have a slope of - 3

a is part of the equation of the second line. b. is not part because x-3y=-3 - 3y=-x-3 y = 1/3x+1 so it is not part of the equation of the second line c is part because y = - 3x-6

d. is part because 6x+2y=2 2y=-6x+2 y = (-6x+2) / 2 y=-3x+1

So yor answer is B.
