Back

Front

What is the slope of a line that is parallel to a line with a slope of 3?

Back

The slope of a line that is parallel to a line with a slope of 3 is also 3.

Front

If two lines have slopes of 2 and -rac{1}{2}, are they perpendicular?

Back

Yes, because the slopes are opposite reciprocals.

Front

What is the relationship between the slopes of parallel lines?

Back

The slopes of parallel lines are equal.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

Identify the slope of the line represented by the equation y = 4x + 1.

Back

The slope of the line is 4.

Front

Identify the slope of the line represented by the equation y = -3x + 5.

Back

The slope of the line is -3.

Front

Which of the following lines is parallel to y = 2x + 3? y = 2x - 1, y = -rac{1}{2}x + 4, y = 3x + 2

Back

y = 2x - 1 is parallel to y = 2x + 3.

Front

Which of the following lines is perpendicular to y = rac{1}{3}x + 2? y = 3x - 1, y = -3x + 4, y = rac{1}{3}x + 5

Back

y = -3x + 4 is perpendicular to y = rac{1}{3}x + 2.

Front

What is the slope of the line represented by the equation y = -rac{1}{4}x + 2?

Back

The slope of the line is -rac{1}{4}.
