Find the slope of the line satisfying the given conditions. horizontal, through (5, 1)

검증된 단계별 안내

Recall that a horizontal line has a slope of zero because it does not rise or fall as it moves from left to right.

Identify the given point through which the line passes, which is (5, 1).

Since the line is horizontal, its slope is the same everywhere along the line, regardless of the point.

Therefore, the slope of the line passing through (5, 1) and being horizontal is 0.

You can express the equation of this horizontal line as \(y = 1\), but the slope remains \(m = 0\).

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Slope of a Line

The slope of a line measures its steepness and direction, calculated as the ratio of the change in y-values to the change in x-values between two points. It indicates how much y changes for a unit change in x.

Horizontal Lines

A horizontal line runs left to right and has no vertical change, meaning its slope is zero. All points on a horizontal line share the same y-coordinate, regardless of the x-coordinate.

Using a Point to Define a Line

A point on a line provides a specific location through which the line passes. When combined with the line's orientation (e.g., horizontal), it helps determine the equation or slope of the line.
