Types of Slopes

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

A positive slope indicates that as the x-values increase, the y-values also increase, resulting in an upward trend from left to right.

A negative slope indicates that as the x-values increase, the y-values decrease, resulting in a downward trend from left to right.

To identify the slope from a table, calculate the change in y (vertical change) divided by the change in x (horizontal change) between two points.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

In the equation y - 4 = 2/3(x - 3), the slope is 2/3, indicating that for every 3 units moved horizontally, the line moves up 2 units.

The slope of a horizontal line is 0, indicating no vertical change as the x-values change.

The slope of a vertical line is undefined, as there is no horizontal change.

The steeper the slope, the larger the angle the line makes with the horizontal axis.

Slope represents the rate of change between two variables; a steeper slope indicates a greater rate of change.
