Understanding Parallel and Perpendicular Lines

What is a common characteristic of parallel lines?

• They have opposite slopes

• They intersect at a right angle

• They never intersect

• They have the same slope

What is the slope of a line parallel to a line with a slope of -2/3?

• -2/3

• 2/3

• -3/2

• 3/2

What defines perpendicular lines?

• Lines with the same slope

• Lines that never intersect

• Lines that intersect at a 90-degree angle

• Lines that are parallel to each other

How do you find the slope of a line parallel to another given line?

• By dividing the slope of the given line

• By finding the opposite reciprocal slope

• By finding the same slope

• By subtracting the slope of the given line

What property do parallel lines share?

• They intersect at some point

• They are always vertical

• They have reciprocal slopes

• They have identical slopes

What is the slope of a line that is parallel to a line with an equation of 5y - 2x = 7?

• -5/2

• 2/5

• -2/5

• 5/2

What is the slope of a line perpendicular to a line with a slope of 3/4?

• -3/4

• 3/4

• -4/3

• 4/3

How can you determine if two lines are perpendicular?

• If one's slope is the opposite reciprocal of the other's

• If they never intersect

• If they have the same slope

• If they intersect at a 45-degree angle

What is the slope of a line perpendicular to a line with an equation of 3x - 4y = 2?

• -4/3

• -3/4

• 3/4

• 4/3
