Front

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

Back

The equation is y = 2x - 5.

What slope is parallel to m = 3/4?

Back

The slope parallel to m = 3/4 is 3/4.

Front

Define parallel lines in geometry.

Back

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

Front

Define perpendicular lines in geometry.

Back

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