Answer:
Gradient of line A = 0.8
Gradient of line B = 0.75
Therefore the lines are not parallel
Step-by-step 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
Answer:
#1 = 0.75
#2 =0.4
#3 = 1/5
#4 = 9/20
Hope this helps :)

Sorry, I wrote an answer, but it was wrong.
3. is the lowest common factor of these
This is quick to see with square root of 81 being 9 and the middle sign being a minus. (a) 2x-9 is the answer
