(3.5) Flashcard

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are the same.

Front

Which equation represents a line parallel to y = 5x - 3 that passes through (0, 4)?

Back

y = 5x + 4

Front

What slope is parallel to m = 4?

Back

4

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

Are the lines y = 3x + 2 and y = 3x - 3 parallel, perpendicular, or neither?

Back

Parallel

Front

Define 'slope'.

Back

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

Front

What is the slope of a line that is horizontal?

Back

0

Front

What is the slope of a line that is vertical?

Back

Undefined.

Front

If two lines have slopes of 2 and -1/2, are they parallel, perpendicular, or neither?

Back

Perpendicular.

Front

What is the slope-intercept form of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.
