Ontario Mathematics Proficiency Practice Test

Question: 1 / 400

Which of the following describes a line with a negative slope?

The line goes up as it moves from left to right

The line goes down as it moves from left to right

A line with a negative slope indicates that as you move along the line from left to right, the value of the dependent variable (usually \(y\)) decreases. This downward trend is characteristic of a negative slope, which can be visualized as the line falling as it progresses horizontally. Therefore, the description that states the line goes down as it moves from left to right accurately captures this behavior associated with a negative slope.

In contrast, a line that goes up from left to right describes a positive slope, while a horizontal line indicates no slope at all, and a vertical line is considered to have an undefined slope. These descriptions clarify why they do not represent a line with a negative slope.
