What is the slope of the line that represents an inverse relationship between two variables?

Explanation:
An inverse relationship means one variable increases while the other decreases, so the slope must be negative. Slope tells you how y changes as x increases; if y goes down as x goes up, the slope is negative. Visually, that shows up as a line that falls when you move from left to right—describing it as descending from upper left to lower right. A horizontal line would have zero slope and wouldn’t reflect an inverse relationship, while an ascending line would have a positive slope and indicate a direct relationship.
