Back

-1/2

Front

What slope is parallel to m = 4?

Back

4

Front

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

Back

y = -2/3x + 2

Which line is parallel to y = 5x - 3 and goes 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.

What is the negative reciprocal of 3?

Back

-1/3

Front

If a line has a slope of 1/4, what is the slope of a line perpendicular to it?
