Welcome to the deck on real-life graphs. In maths, graphs aren't just for abstract equations; they're powerful tools for showing relationships between real-world quantities. We'll focus on two main types: conversion graphs, for changing between units, and distance-time graphs, for describing a journey.

Let's start with conversion graphs. A conversion graph is usually a straight line that helps you quickly switch between two different units of measurement, like converting pounds to dollars, or kilograms to pounds, without doing any calculations.

To use a conversion graph, you find your starting value on one axis, either the horizontal or vertical one. From that point, you move across or up until you hit the line on the graph. Then, you move from the line to the other axis to read off the converted value.
