Plotting linear graphs Going from rule to graph. To sketch a linear graph from a rule, determine two points that satisfy the rule and connect them with a straight line. Two commonly used methods are: ...

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 ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

In a linear function, the output values increase or decrease at a constant rate. In a nonlinear function, the output values do not change at a constant rate. 2. Matching tables with graphs. Once ...

If we set β = f(1), then for any real number x, we have f(x) = βx and the graph of this function is the straight line in the plane passing through the origin with slope β.

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 ...
