Parallel, Perpendicular, neither practice

Front

What are parallel lines?

Back

Lines that have the same slope and never intersect.

Front

What are perpendicular lines?

Back

Lines that intersect at a right angle (90 degrees) and have slopes that are opposite reciprocals.

Front

What does it mean for two lines to be neither parallel nor perpendicular?

Back

They intersect at an angle that is not 90 degrees and do not have the same slope.

Front

What is the slope of a line in the equation y = mx + b?

Back

The slope is represented by 'm'.

Front

If two lines have slopes of 3 and 3, what can we say about them?

Back

They are parallel.

Front

If the slope of one line is 2, what is the slope of a line that is perpendicular to it?

Back

The slope would be -1/2 (the opposite reciprocal).

Front

What is the point-slope form of a linear equation?

Back

y - y1 = m(x - x1) where (x1, y1) is a point on the line.

Front

How do you determine if two lines are parallel using their equations?

Back

Check if their slopes are equal.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

Their slopes are opposite reciprocals.

Front

What is the slope of the line represented by the equation y = -4x + 5?

Back

The slope is -4.
