Revise how to work out the equation of a straight line using coordinates and the gradient, and vice versa. BBC Bitesize Scotland SQA National 5 Maths.

To discover the linear relationship, we could measure the weight of three individuals at each height and apply linear regression to model the mean weight as a function of height using a straight ...

The Nernst equation. You probably recognise equation 1 as the Nernst equation. This equation defines the relation between the concentrations of an ion on either side of a membrane that it perfectly ...

The least-squares criterion is a method of measuring the accuracy of a line in depicting the data that was used to generate it. That is, the formula determines the line of best fit.

Simple linear regression relates two variables (X and Y) with a straight line (y = mx + b), while nonlinear regression relates the two variables in a nonlinear (curved) relationship.

Polynomial equations have long served as a cornerstone of mathematical analysis, offering a framework to understand functions, curves, and dynamic systems. In recent years, the study of these ...

In the case of straight-line depreciation, the amount depreciated is the same year over year. This simplifies the equation. The formula for calculating straight-line depreciation is: Annual ...
