Answer:

a)  when the slopes are equal

Step-by-step explanation:

The slopes of lines can be used to define the nature of lines.

Two parallel lines have equal slopes and the product of slopes of perpendicular lines is -1.

Hence, we can conclude that two distinct non-vertical lines parallel when

a)  when the slopes are equal ..

So, option a is correct ..

Answer: Option a.

Step-by-step explanation:

By definition:

- Two lines are parallel if they have the same slope.

- Vertical lines are parallel.

- The slope of any Vertical line is undefined.

- A Non-vertical line has a defined slope.

Therefore, based on this, we can make the following conclusion is: Two distinct nonvertical lines are parallel when the slopes are equal.

Then, the correct answer is Option a.
