Question

How do you know two lines are parallel?

Answer 1

Answer:

D) Their slopes are equal.

Step-by-step explanation:

For a line to be parallel, both lines need to be going at the same angle forever and never intersect. So if the slopes of the lines are equal, both of the lines would be at the same angle going the same direction. It does not matter where the lines are on the graph! It can be on top of the other line or far away from the other line, it just needs to have the same slope.

Answer 2

Answer:

4) Their slopes are equal

Step-by-step explanation:

Parallel lines with the same slope will never meet because they have the same slope
