Key Concepts

Line Graph

A line graph is a visual tool used to display data points connected by straight lines. It helps in illustrating trends over a continuous range, such as how one value changes in relation to another, making it ideal for showing the relationship between an original price and a sale price.

Coordinate System

A coordinate system allows data to be plotted on a plane using two perpendicular axes: the horizontal axis for one variable and the vertical axis for the other. This system helps to precisely locate the value pairs, such as original price and sale price, and understand how they interrelate.

Independent and Dependent Variables

In graphing, the independent variable is typically placed on the horizontal axis and represents the input or cause, while the dependent variable is placed on the vertical axis and represents the output or effect. In the context of comparing prices, the original price is the independent variable and the sale price, influenced by the discount, is the dependent variable.

Data Transformation

Data transformation involves applying a specific rule or function to convert one set of values into another. In this case, the coupon discount acts as a transformation function that reduces the original price to yield the sale price, a concept central to understanding how discounts affect pricing in a linear relationship.
