Going from graph to rule. To determine the rule for a given linear graph, locate two points on the graph and use these to calculate the gradient and establish the \(y\)-intercept. Two commonly used ...

When learning algebra, one of the most crucial skills to acquire is understanding how to graph linear equations. It helps you visualize relationships between variables and solve mathematical problems.

Revise how to recognise and determine the equation of a quadratic function from its graph. BBC Bitesize Scotland revision for SQA National 5 Maths.

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. Travel graphs. Learn about travel graphs with BBC Bitesize Key Stage 3 Maths.

In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph of a non-linear function is a curved line. A curved line is a line whose direction ...

The same thing would be true for the first function above, f(x) = x²: n² would equal n.This would be a weird mathematics indeed (there are algebras in which this happens for some nonunit ...

It describes an emerging approach to solving linear systems of equations that relies heavily on techniques from graph theory. OK, I admit it. Solving systems of equations is one of those "supposed to ...

The linear function is popular in economics. It is attractive because it is simple and easy to handle mathematically. It has many important applications. Linear functions are those whose graph is a ...
