Writing Parallel and Perpendicular Lines Flashcard

Front

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

Back

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

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 -3.

Front

Write the equation of a line PERPENDICULAR to the line y = 5x + 1 that passes through the point (2, 3).

Back

y = -1/5x + 4.

Front

Write the equation of a line PARALLEL to the line y = -2x + 3 that passes through the point (1, 1).

Back

y = -2x + 3.

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

Determine if the lines y = 2x + 3 and y = 2x - 5 are parallel, perpendicular, or neither.

Back

The lines are parallel.

Front

Determine if the lines y = -1/2x + 4 and y = 2x - 1 are parallel, perpendicular, or neither.

Back

The lines are perpendicular.

Front

Write the equation of a line PERPENDICULAR to the line y = 4x + 2 that passes through the point (0, 1).

Back

y = -1/4x + 1.

Front

Write the equation of a line PARALLEL to the line y = 3x + 5 that passes through the point (2, 2).

Back

y = 3x - 4.
