Finding Slopes of Parallel and Perpendicular Lines

What is the relationship between the slopes of two parallel lines?

• One slope is double the other.

• They have no relationship.

• They have negative reciprocal slopes.

• They have the same slope.

If two lines are parallel, what can be said about their intersection?

• They will intersect at one point.

• They will never intersect.

• They will intersect at right angles.

• They will intersect at multiple points.

What is the relationship between the slopes of two perpendicular lines?

• They have the same slope.

• They have no relationship.

• They have negative reciprocal slopes.

• One slope is double the other.

What does 'flip and switch' refer to in the context of perpendicular lines?

• Flipping the slope and switching its sign.

• Flipping the line and switching its direction.

• Flipping the graph and switching the axes.

• Flipping the coordinates and switching the points.
