In this deck, we'll explore the world of graphs. We'll start with the basics of coordinates, which are like a map reference for a specific point. Then, we'll learn how to use these coordinates to draw straight-line graphs from their equations.

Imagine two lines crossing at a right angle. The horizontal line is called the x-axis, and the vertical line is the y-axis. This setup is called a coordinate grid or a Cartesian plane. The point where the axes cross is called the origin.

To find any point on the grid, we use a pair of numbers called coordinates, written inside brackets like (x, y). The first number tells you how far to go along the x-axis, and the second tells you how far to go up or down the y-axis. A good way to remember the order is 'along the corridor, then up or down the stairs'.
