Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in ...

A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight line or a smooth curve. A linear function has an equation of the form \(y = mx + c\).

The straight-line method (or straight-line basis) uses a built-in function, SLN ... a grid-like format of rows and columns. By creating graphs and tables, Excel users can compute and visualize ...

In one variable, a linear function can ... scatter plots on a graph following a certain pattern but that pattern is not linear, meaning the representation is not a straight line.
