Key Concepts

Midpoint Formula

The Midpoint Formula is used to find the value or coordinate that lies exactly halfway between two known points. In the context of linear data, such as sales figures at two different times, it provides a way to calculate an estimate at a time that is equidistant from the endpoints, ensuring the assessment of the trend remains balanced.

Linear Interpolation

Linear Interpolation is a method used to estimate unknown values that fall within the range of two known data points. Assuming a linear relationship between the points, this technique calculates the estimated value by proportionally balancing the differences, making it particularly useful when estimating intermediate values in a sequence.

Average Rate of Change

The Average Rate of Change refers to how much a quantity, such as sales, changes on average for each unit increase in the independent variable, typically time. It is a fundamental concept in linear models to determine the slope, indicating how quickly or slowly a value is increasing or decreasing over a given period.
