Exploring Advanced Math Vocabulary: Adding and Subtracting Rational Expressions

What is the main topic of lesson one four one five?

• Parallel and perpendicular lines

• Vocabulary terms

• Graphing functions

• Algebraic equations

What is a key characteristic of parallel lines?

• They have different slopes

• They intersect at a 90-degree angle

• They have the same slope

• They are always horizontal

How can you determine if two lines are parallel?

• By measuring the angle between them

• By checking if they intersect

• By comparing their slopes

• By checking if they are vertical

What notation is used to indicate that two lines are parallel?

• m ⊥ n

• m ≠ n

• m || n

• m = n

What does the notation 'm || n' signify?

• m is parallel to n

• m is equal to n

• m is not equal to n

• m is perpendicular to n

What are the slopes of perpendicular lines?

• Equal

• Opposite reciprocals

• Both positive

• Both negative

What does 'opposite' refer to in the context of perpendicular slopes?

• The angle between the lines

• The direction of the lines

• The sign of the slopes

• The length of the lines

What does 'reciprocal' mean in the context of perpendicular slopes?

• To flip the fraction

• To multiply the fractions

• To subtract the fractions

• To add the fractions

Which of the following pairs of slopes would indicate perpendicular lines?

• 5/6 and 6/5

• 3/4 and 4/3

• 2/3 and -3/2

• 1/2 and 2/1

At what angle do perpendicular lines intersect?

• 90 degrees

• 120 degrees

• 60 degrees

• 45 degrees
