Exploring Slope with Parallel and Perpendicular Lines

What does a positive slope indicate about the direction of a line?

• The line moves upwards

• The line moves downwards

• The line is vertical

• The line is horizontal

How is slope typically represented?

• As a whole number

• As a decimal

• As a percentage

• As a fraction

What type of slope do horizontal lines have?

• Undefined

• Zero

• Negative

• Positive

If a line goes straight up and down, what is the slope of the line?

• Undefined

• Negative

• Positive

• Zero

What method is preferred for finding the slope when given a graph?

• Using a calculator

• Rise over run

• Plotting new points

• Change in x over change in y

What do parallel lines share in common regarding their slopes?

• Same slopes

• Opposite slopes

• No slopes

• Different slopes

How can you quickly check if two lines are perpendicular using a physical object?

• Using a compass

• Using a sheet of paper

• Using a ruler

• Using a protractor

What is the slope of a line that is perpendicular to another line with a slope of 2?

• -1/2

• 1/2

• 2

• -2

If two lines intersect but are not perpendicular, what can be said about their slopes?

• They are different but not reciprocals

• They are undefined

• They are opposite reciprocals

• They are the same

What is the correct way to construct a line parallel to another if given a point and slope?

• Use the same slope and the given point

• Use the opposite slope and the given point

• Use the same slope and any point

• Use the reciprocal slope and any point
