Front

If two lines have slopes of 3/2 and 2/3, what can be said about their relationship?

Back

They are neither parallel nor perpendicular.

Front

How do you determine the slope of a line that is perpendicular to another line given by the equation y = 3/2x + 6?

Back

The slope of the perpendicular line is the negative reciprocal of 3/2, which is -2/3.

Front

What is the relationship between the slopes of parallel lines?

Back

Parallel lines have the same slope.

Front

What is the relationship between the slopes of perpendicular lines?

Back

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

Front

If a line has a slope of -4, what is the slope of a line that is parallel to it?

Back

-4

Front

If a line has a slope of 1/5, what is the slope of a line that is perpendicular to it?

Back

Front

What is the slope-intercept form of a line?

Back

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