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).

What does a positive slope indicate about a line?
Back
A positive slope indicates that as the x-coordinate increases, the y-coordinate also increases, meaning the line rises from left to right.

Back
The slope of a horizontal line is 0, indicating no rise as the x-coordinate changes.

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 is 0, leading to division by zero.

FLASHCARD QUESTION
Front
If a line has a slope of 3, what does this mean?
Back
A slope of 3 means that for every 1 unit increase in x, the y value increases by 3 units.
