What do parrall lines look like?

Answer 1

If two or more lines are said to be parallel to one another, it means that they never intersect and that they have identical slopes. If they are expressed as equations (in the format y = mx + b), then you simply look to see if the value for m is the same for both.

For example, the following lines would all be parallel to one another:

y = 4x + 5
y = 4x + 8
y = 4x - 3
