Answer:
Step-by-step explanation:
If two lines are parallel, their slopes (gradients) will be the same.
Ensure both line equations are in the format y = mx + b (where m is the slope and b is the y-intercept):
Line L1: y = 2x + 5
Line L2: 2y - 4x = 6
⇒ 2y = 4x + 6
⇒ y = 2x + 3
As the slopes of L1 and L2 are both 2 and therefore the same, this proves that the two lines are parallel.
