FLASHCARD QUESTION

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.

2.

FLASHCARD QUESTION

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees). Their slopes are negative reciprocals of each other.

3.

FLASHCARD QUESTION

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.

4.

FLASHCARD QUESTION

Front

What is the slope of a line in the equation y = mx + b?

Back

In the equation y = mx + b, 'm' represents the slope of the line.

5.

FLASHCARD QUESTION

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

FLASHCARD QUESTION

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.

7.

FLASHCARD QUESTION

Front

What is the slope of the line y = 4x + 7?

Back

The slope of the line y = 4x + 7 is 4.
