Parallel and Perpendicular Practice

Front

What is the slope of a line parallel to a line with slope m = 3/4?

Back

The slope of a line parallel to m = 3/4 is also 3/4.

Front

If two lines have the same slope, what can we say about them?

Back

The two lines are parallel.

Front

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

Back

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

Front

What is the slope of a line perpendicular to a line with slope m = -2/3?

Back

The slope of a line perpendicular to m = -2/3 is 3/2.

Front

How can you determine if two lines represented by equations are parallel?

Back

Two lines are parallel if they have the same slope.

Front

What does the equation y = mx + b represent?

Back

It represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

What is the slope of the line represented by the equation 2x + 3y = 6?

Back

The slope is -2/3 after rearranging to slope-intercept form.

Front

In the equation y = 3x - 3, what is the slope?

Back

The slope is 3.

Front

What type of lines do the equations y = -2/3x + 2 and y = 3/2x + 9 represent?

Back

They represent perpendicular lines.

Front

If two lines intersect at a right angle, what can we conclude about their slopes?

Back

Their slopes are negative reciprocals.
