Question

Find the values of x and y for which the lines are parallel.


x = 72, y = 68


x = 68, y = 72


x = 46, y = 72


x = 68, y = 74

Answer 1

The lines are parallel when the slopes of the lines are equal. Since the equations are in the form x = a, y = b, the slope is undefined.

Therefore, none of the given values of x and y will result in parallel lines.
