Types of Slopes (2)

A positive slope indicates that as the x-values increase, the y-values also increase, resulting in an upward trend on a graph.

A negative slope indicates that as the x-values increase, the y-values decrease, resulting in a downward trend on a graph.

A zero slope represents a horizontal line where the y-value remains constant as the x-value changes.

An undefined slope represents a vertical line where the x-value remains constant as the y-value changes.

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

The slope is undefined because the x-coordinates are the same, indicating a vertical line.

The slope is 2, calculated as (6 - 2) / (3 - 1) = 4 / 2 = 2.

A line that decreases from left to right has a negative slope.

A line that increases from left to right has a positive slope.

A zero slope is represented by a horizontal line on a graph.
