Which statement is true about the graphs of the two lines y = –6 and x =1/6 ?

A) The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = 1/6 is a vertical line with a slope of 0.

B). The lines are perpendicular to each other because the graph of y = –6 is a vertical line with a slope that is undefined, and the graph of x = 1/6 is a horizontal line with a slope of 0.

C) The lines are perpendicular to each other because the graph of y = –6 is a vertical line with a slope of 0, and the graph of x = 1/6 is a horizontal line with a slope that is undefined.

D) The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope of 0, and the graph of x = 1/6 is a vertical line with a slope that is undefined.
