T3 Review Slopes + Eq's Parallel & Perp. Lines

Front

What is the slope of two parallel lines?

Back

The slope of two parallel lines is the same.

Front

What is the slope of two perpendicular lines?

Back

The slope of two perpendicular lines are opposite reciprocals.

Front

Define opposite reciprocals in terms of slope.

Back

Opposite reciprocals are two numbers whose product is -1, meaning one is the negative inverse of the other.

Front

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

Back

The slope of a line perpendicular to it would be -1/2.

Front

What is the general form of the equation of a line?

Back

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

Front

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

Back

Two lines are parallel if they have the same slope.

Front

How do you determine if two lines are perpendicular from their equations?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is the slope of the line represented by the equation y = 4x + 3?

Back

The slope of the line is 4.

Front

What is the slope of the line represented by the equation y = -1/2x + 5?

Back

The slope of the line is -1/2.

Front

If two lines have slopes of 3 and -1/3, what can be said about their relationship?

Back

The lines are perpendicular.
