PreCal Chapter 1: Functions and Graphs Flashcards

Slope

• Represents the steepness of a line in the coordinate plane.
• Calculated using the formula: m = (y2 - y1) / (x2 - x1)
• Also expressed as the change in y (vertical) over the change in x (horizontal).

Point-Slope Form

• A useful equation for linear functions that describes the relationship between points on a line.
• Given by the formula: y - y1 = m(x - x1)
• m represents the slope, and (x1, y1) is a specific point on the line.

Positive and Negative Slopes

• A line with a positive slope (m > 0) rises as it moves from left to right.
• A line with a negative slope (m < 0) falls as it moves from left to right.
• The slope indicates the direction of the line: positive slopes indicate upward movement, while negative slopes indicate downward movement.
