Writing Parallel and Perpendicular Equations of Lines.

Front

What are parallel lines?

Back

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

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees). Their slopes are opposite reciprocals.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm' in the equation of a line.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

How do you determine if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is an undefined slope?

Back

An undefined slope occurs in vertical lines, where the change in x is zero.

Front

What is the slope of a line parallel to the line with equation y = 2x + 3?

Back

The slope of a line parallel to y = 2x + 3 is 2.

Front

What is the slope of a line perpendicular to the line with equation y = -rac{1}{3}x + 4?

Back

The slope of a line perpendicular to y = -rac{1}{3}x + 4 is 3.

Front

Write the equation of a line parallel to y = 5x - 1 that passes through the point (2, 3).

Back

y = 5x - 7.

Front

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

Back

y = -rac{1}{4}x + rac{5}{4}.
