Final answer:
The slope can be positive, negative, or zero in Mathematics. A positive slope indicates an increasing line, a negative slope indicates a decreasing line, and a slope of zero represents a horizontal line.
Step-by-step explanation:
In mathematics, the slope is a measure of how steep a line is. It represents the ratio of the vertical change (the rise) to the horizontal change (the run) between any two points on the line. The slope can be positive, negative, or zero.
A positive slope indicates that the line is increasing as the x-values increase. For example, with a slope of 3, there is a rise of 3 on the vertical axis for every increase of 1 on the horizontal axis.
A negative slope indicates that the line is decreasing as the x-values increase. For example, with a slope of -3, there is a decrease of 3 on the vertical axis for every increase of 1 on the horizontal axis.
A slope of zero indicates a horizontal line, where the y-values remain constant regardless of the change in x-values.
