Final Exam LT#1: Parallel and Perpendicular Lines

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They have the same slope but different y-intercepts.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees). Their slopes are opposite reciprocals.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm' in the equation of a line (y = mx + b).

Front

How do you find the slope of a line given two points?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line y = 2x - 7?

Back

The slope of the line y = 2x - 7 is 2.

Front

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

Back

If two lines have the same slope, they are parallel.

Front

What is the opposite reciprocal of a slope of 3?

Back

The opposite reciprocal of a slope of 3 is -1/3.

Front

What is the slope of a line perpendicular to y = -3x + 4?

Back

The slope of a line perpendicular to y = -3x + 4 is 1/3.

Front

Which line is parallel to y = -1/2x + 3?

Back

y = -1/2x + 1 is parallel to y = -1/2x + 3.

Front

What is the slope of a line perpendicular to a line with slope 5/8?

Back

The slope of a line perpendicular to a line with slope 5/8 is -8/5.
