Back
The slope of a line is a measure of its steepness, usually represented as 'm'. It is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.
2.
FLASHCARD QUESTION
Front
How do you calculate the slope between two points (x1, y1) and (x2, y2)?
Back
The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

FLASHCARD QUESTION
Front
What does a positive slope indicate about a line?
Back
A positive slope indicates that as you move from left to right along the line, the line rises. This means that the y-value increases as the x-value increases.

FLASHCARD QUESTION
Front
What does a negative slope indicate about a line?
Back
A negative slope indicates that as you move from left to right along the line, the line falls. This means that the y-value decreases as the x-value increases.

FLASHCARD QUESTION
Front
What is the slope of a horizontal line?
Back
The slope of a horizontal line is 0, indicating that there is no vertical change as you move along the line.

FLASHCARD QUESTION
Front
What is the slope of a vertical line?
Back
The slope of a vertical line is undefined because the change in x (run) is 0, leading to division by zero in the slope formula.

FLASHCARD QUESTION
Front
If a line rises 3 units for every 2 units it runs, what is the slope?
Back
