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 = 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 = 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 = 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 = is a vertical line with a slope that is undefined.

Right answer: D

1. Lines with the form y=c, where c is a constant, like y=2, y=-3, y=21,7 ... etc are all lines parallel to the x-axis, so they are horizontal lines.

Horizontal lines have 0 inclination, so slope=0

2. Lines of the form x=c, where c is a constant, like x=5,4  , x= 7 etc are lines parallel to the y-axis, so they are vertical lines.

Vertical lines are lines with undefined slope
