What does the slope formula represent?

• A. The vertical distance only
• B. The horizontal distance only
• C. The ratio of change in vertical distance to the change in horizontal distance
• D. The sum of vertical and horizontal distances

Answer: (C)

The slope formula represents the ratio of change in vertical distance to the change in horizontal distance, making it an essential concept in understanding the steepness or inclination of a line in a coordinate plane. Specifically, when you calculate the slope, you are determining how much the y-coordinate (vertical distance) changes for each unit of change in the x-coordinate (horizontal distance). This ratio is expressed mathematically as \( m = \frac{y_2 - y_1}{x_2 - x_1} \), where \( y_2 \) and \( y_1 \) are the values of the dependent variable, and \( x_2 \) and \( x_1 \) are the values of the independent variable. This conceptual foundation is critical in various applications, such as determining the slope of a line on a graph, analyzing trends in data, or understanding rates of change in real-life scenarios, such as speed or growth rates. The slope thus provides insights into how two quantities relate to each other when graphed, underlining its importance in mathematics and across different disciplines.

Specifically, when you calculate the slope, you are determining how much the y-coordinate (vertical distance) changes for each unit of change in the x-coordinate (horizontal distance). This ratio is expressed mathematically as ( m = \frac{y_2 - y_1}{x_2 - x_1} ), where ( y_2 ) and ( y_1 ) are the values of the dependent variable, and ( x_2 ) and ( x_1 ) are the values of the independent variable.
