Parallel and Perpendicular Lines

Front

What is the slope of a line that is perpendicular to a line with slope m = 3?

Back

-\frac{1}{3}

Front

If Line 1 has points (-1, 2) and (2, 3) and Line 2 has points (0, 0) and (3, 1), are these lines parallel, perpendicular, or neither?

Back

Parallel

Front

Write an equation for a line that is parallel to y = 2x + 6 and passes through the point (4, 12).

Back

y = 2x + 4

Front

What can be said about the slopes of parallel lines?

Back

The same

Front

What is the slope of a line that is parallel to y = 2x - 7?

Back

2

Front

What is the relationship between the slopes of two perpendicular lines?

Back

They are negative reciprocals.

Front

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

Back

\frac{1}{2}

Front

How do you determine if two lines are parallel using their slopes?

Back

If their slopes are equal.

Front

What is the slope of a line that is perpendicular to a line with slope 1/2?

Back

Front

If two lines have slopes of 3 and -1/3, what can be said about their relationship?

Back

They are perpendicular.
