Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. ... For example, for y = 3x, the y value is always equal to '3 lots' of the x value.

Linear graphs with inferences and applications occupy fully half the book, ... The numerous examples are interesting and suggestive, and all the answers are given at the end.

Unlike a linear, graph, a quadratic graph has an equation which includes an x squared term. ... Example. Using the graph from the previous example to solve the equation \(2x^{2} ...
