Understanding Slopes of Parallel and Perpendicular Lines

What problem did the magician's apprentices face?

• They turned their master into a bear.

• They couldn't find the magic book.

• They forgot the magic spell.

• They lost their magic wands.

What are the equations of the magic rays?

• y = 3x + 4 and y = 3x + 10

• y = 5x + 4 and y = 5x + 10

• y = 2x + 4 and y = 2x + 10

• y = 4x + 4 and y = 4x + 10

In the slope-intercept form y = mx + b, what does 'm' represent?

• The y-intercept

• The constant term

• The x-intercept

• The slope

What is the slope of the equations y = 3x + 4 and y = 3x + 10?

• 10

• 1

• 4

• 3

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

• They are both negative.

• They are equal.

• They are negative reciprocals.

• They are both positive.

What was the result of deploying parallel magic rays at the same time?

• The magic failed.

• A rabbit appeared.

• The master turned into a bear.

• The apprentices disappeared.
