Which of the equations below represents a line parallel to the y-axis? A. x = 4 B. x = - y C. x = y D. x = 4y

x=4

Step-by-step explanation:

x=4 represents a line parallel to y-axis cutting the x-axis at (4,0).

x=-y represents a straight line passing through the origin with a negative slope.

x=y represents a straight line with positive slope and passing through the origin.

x=4y represents a straight line passing through origin having a positive slope.
