Question

For x = 3, w = 6:
Line a: slope = -3/2
Line d: slope = -3/2
Since the slopes are equal, line a is parallel to line d for x = 3 and w = 6.

For x = 5, w = 3:
Line a: slope = 2/3
Line d: slope = -3/2
The slopes are not equal, so line a is not parallel to line d for x = 5 and w = 3.

For x = 1, w = 5:
Line a: slope = -5/1 = -5
Line d: slope = -3/2
The slopes are not equal, so line a is not parallel to line d for x = 1 and w = 5.

For x = 3, w = 5:
Line a: slope = -5/2
Line d: slope = -3/2
Since the slopes are equal, line a is parallel to line d for x = 3 and w = 5.

Therefore, line a is parallel to line d for x = 3, w = 6 and x = 3, w = 5.

Answer 1

However, line a is not parallel to line d for x = 5, w = 3 and x = 1, w = 5.
