Question

Which of the following lines is parallel to x=8?
3y=16
x=7
x=y
y=8

Answer 1

Answer: x=7 is the line parallel to the given line x=8 .

Explanation:

Parallel lines are the lines which are always same distance apart and never intersect. The given line is x=8 with intersects the x axis at x=8 and it is parallel to y axis with slope infinite or not defined. So from the given options only x=7 is the line which is equidistant(same distance between them at any point) never intersect x=8 and is parallel to y - axis. Therefore x=7 is to line which is parallel to x=8.

Answer 2

Parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point. Therefore, from the choices listed above, the correct answer should be the second option. The line that is parallel to x=8 should be x =7. Hope this answers the question. Have a nice day.
