Question

Which statement is true for the two lines y = 6 and x = 3?
A. the two lines are parallel
B. The two lines are perpendicular
c. The two lines are neither parallel nor perpendicular
D. The two lines intersect at more than one point (i know this answer is wrong)

Answer 1

y= something lines are always horizontal as the y value cannot change. X = something lines are always vertical as the x-corrdinate cannot change (they are constants). So they are perpendicular. This would be true for x=k and y=l whatever values of K and l you use.
