If two lines run parallel to each other, will they both share the same gradient?

Question:

If two lines run parallel to each other, will they both share the same gradient? Also does it mean that if the gradients of two lines are the same, that they are parallel?

Answer:

Yes, if the lines are parallel, this implies that their gradients are the same and vise versa ( if gradients are the same it means that the lines are parallel.
