Parallel and Perpendicular Lines

Front

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

Back

The slope is 2.

Front

Which line is perpendicular to y = 3/2x + 6 and passes through the point (-3, 4)?

Back

y = -2/3x + 2.

Front

What is the slope that is perpendicular to m = 5/8?

Back

The slope is -8/5.

Front

Are the lines y = 6x + 2 and y = -6x + 2 parallel, perpendicular, or neither?

Back

They are neither.

Front

Which line is parallel to y = 5x - 3 and passes through the point (0, 4)?

Back

y = 5x + 4.

Front

Define parallel lines.

Back

Parallel lines are lines in a plane that never meet; they have the same slope.

Front

Define perpendicular lines.

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees); their slopes are negative reciprocals.

Front

What is the negative reciprocal of 3/4?

Back

The negative reciprocal is -4/3.

Front

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

Back

They are perpendicular.

Front

What is the slope of a line that is parallel to the x-axis?

Back

The slope is 0.
