Parallel lines have the same slope. Think slope as the angle between the line and the x-axis. So it makes sense that the slopes have to be equal.

The standart form formula is

The slope is:

If you can't remember this, you can calculate the slope by selecting two random points on the line

The slope is:

So any line with slope

So we can say this:

**A line is parallel to another if and only if their slopes are equal.**
