Writing Equations for Parallel & Perpendicular Lines

Front

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

Back

The slope of a line that is perpendicular to a line with a slope of -3 is 1/3.

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 negative reciprocals of each other.

Front

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

Back

y = 2x + 1.

Front

Write the equation of a line that is perpendicular to y = 4x - 2 and passes through the point (2, 1).

Back

y = -1/4x + 3/2.

Front

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

Back

They are parallel.

Front

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