Parallel & perpendicular lines (Algebra I)

Front

What is the slope of a line that is perpendicular to the line represented by the equation y = mx + b?

Back

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

Front

What is the slope of a line that is parallel to the line represented by the equation y = mx + b?

Back

The slope of a line that is parallel to another line with slope m is also m.

Front

Write the equation of a line that is perpendicular to y = 2x + 3 and passes through the point (-2, 4).

Back

Front

Write the equation of a line that is parallel to y = 5x - 3 and passes through the point (0, 4).

Front

What do you call two lines that never intersect?

Back

Parallel lines.

Front

What do you call two lines that intersect at a right angle?

Back

Perpendicular lines.

Front

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

Back

They are perpendicular lines.

Front

Determine if the lines y = 6x + 2 and y = -6x + 2 are parallel, perpendicular, or neither.

Back

They are neither.

Front

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

Back

The slope is -1/2.

Front

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

Back

The slope of the parallel line is also 2.
