Question

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

Answer 1

b

Answer 2

y = -3x + 5. Any line parallel to this line, should have slope : -3.
Transform all equation to the slope form
A. y = -3x + 2
B. x - 3y = -3 -> 3y = x + 3 -> y = x/3 + 1/3
C. 3x + y = -6 -> y = -3x - 6
D. 6x + 2y = 2 -> 2y = -6x + 2 -> y = -3x +1
