Answer:
Step-by-step explanation:
Put what you are given in the form of
y = mx + b
If both equations have the same m, the lines are parallel. For example
y = 4x + 10
y = 4x + 20
These two lines are parallel.
However
y = 8x + 40
y = 4x + 10 are not parallel even though it looks like m could be made the same by taking out 4 in each. Check them out on the graph below.
