A linear equation is one that has the form ax by = c. The variables x and y are variables, while the constants a, b, and c are constants. y = 4x - 3 is an example of a linear equation. What are fixed ...

This is a rather simplistic example. In reality, we know there are many factors that influence a person's salary. This is where multivariate linear regression comes into play. For example, suppose you ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. ... For example y = 2x + 1. The y value is always '2 lots' of the x value plus 1.

Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. ... For example, if you are graphing the relationship between marketing spending and revenue, ...

In this example, when \(k = -\frac{12}{5}\) the equations will have the same gradient and different \(y\)-intercepts. As a result, the lines are parallel, and there are no solutions. For infinite ...
