Review of Slope and Parallel/Perpendicular Lines

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are identical.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

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

Back

They are parallel.

Front

If the slopes of two lines are negative reciprocals of each other, what is their relationship?

Back

They are perpendicular.

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

How do you determine if two lines intersect?

Back

Two lines intersect if they have different slopes.

Front

What is the slope of the line y = 5x - 3?

Back

The slope is 5.

Front

What is the slope of the line y = -2/3x + 2?

Back
