If line 1 has a slope of 2/5, how do you find the slope of line 2 if the two lines are parallel?

Answer 1

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 #2/5#

If two lines are parallel, they have the same slope. Therefore, if line 1 has a slope of 2/5, then line 2, being parallel to line 1, also has a slope of 2/5.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
