(3.5) Flashcard

Front

What is the slope of a line parallel to a line with slope m = 4?

Back

The slope of a line parallel to m = 4 is also 4.

Front

If two lines have the same slope, what can we say about them?

Back

The lines are parallel.

Front

What are the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

What is the equation of a line that goes through the point (0, 4) and is parallel to y = 5x - 3?

Back

The equation is y = 5x + 4.

Front

What is the slope that is perpendicular to m = 5/8?

Back

The slope that is perpendicular to m = 5/8 is -8/5.

Front

Define 'slope' in the context of a linear equation.

Back

Slope is a measure of the steepness of a line, calculated as the rise over run.

Front

What does it mean for two lines to be 'parallel'?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

What does it mean for two lines to be 'perpendicular'?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

If a line has a slope of 2, what is the slope of a line that is perpendicular to it?

Back

The slope of a line that is perpendicular to a line with slope 2 is -1/2.

Front

What is the slope of a line that is horizontal?

Back

The slope of a horizontal line is 0.
