The slope measures the "slant" of a line. Two lines are parallel if they has the same "slant" (or if neither is "slanted".)

So, two lines are parallel if they have equal slopes (or if neither line has a slope -- that is, if both are vertical.)

In order for your line 2 top be parallel to line 1, it must have slope
