Parallel and Perpendicular Slopes

Front

What is the slope of a line perpendicular to the line y = ½x + 4?

Back

-2

Front

True or False: Perpendicular lines have the same slope.

Back

False

Front

What describes the relationship between the slopes m = 4 and m = -1/4?

Back

Neither (they are not parallel or perpendicular).

Front

What describes the relationship between the slopes m = 3/4 and m = 4/3?

Back

Neither (they are not parallel or perpendicular).

Front

True or False: The slopes of perpendicular lines are negative reciprocals.

Back

True.

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, represented as 'm' in the equation y = mx + b.

Front

What is the slope of a line parallel to the line y = 3x + 2?

Back

3 (parallel lines have the same slope).

Front

If two lines have slopes m1 and m2, what condition must be met for them to be perpendicular?

Back

m1 * m2 = -1 (the slopes are negative reciprocals).

Front

What is the slope of a horizontal line?

Back

0 (horizontal lines have a slope of zero).

Front

What is the slope of a vertical line?

Back

Undefined (vertical lines do not have a defined slope).
