Answer:
Gradient of line A = 0.8
Gradient of line B = 0.75
Therefore the lines are not parallel
Explanation:
1. Rearrange the equation of line A into the form Y=mX + C in order to find the gradient of line A which m in the equation represents the gradient.
2. Use the gradient formula, (y2-y1)/(x2-x1) to find the gradient of line B
Since the both have different gradient. It means that they are not parallel
