12/5 - Choose parallel, perpendicular or neither

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). The slopes of perpendicular lines are negative reciprocals of each other.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope and different y-intercepts.

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 does it mean if two lines are neither parallel nor perpendicular?

Back

If two lines are neither parallel nor perpendicular, they intersect at an angle that is not 90 degrees.

Front

What is the slope-intercept form of a line?

Back

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept.

Front

Convert the equation 4y + 2x = 12 to slope-intercept form.

Back

y = -1/2x + 3.

Front

What is the slope of the line y = 2x - 17?

Back

The slope is 2.

Front

What is the slope of the line y = -2x + 2?

Back

The slope is -2.

Front

Determine if the lines y = 3x + 6 and 3x + y = 6 are parallel, perpendicular, or neither.

Back

Perpendicular.
