Tables and Values

A table of values lists pairs of \(x\) and \(y\) that follow a rule, ready to be plotted on the number plane. In NSW Year 8 maths, students complete tables by substituting into rules such as \(y = 10 - 3x\) and by continuing a pattern (NESA outcome MA4‑LIN‑C‑01).

You will substitute negative, decimal and fraction values, follow the order of operations when a rule has a subtraction or a fraction bar, and continue a pattern to find missing values or a value much further along. You will also work backwards from a known \(y\)-value to \(x\), handle uneven gaps between the \(x\)-values, spot the mistake in someone else's table, and build tables for the temperature on a mountain climb and the cost of movie tickets. It is part of Year 8 Graphing Linear Equations.
