Recognising Graphs and Transformations of Graphs

Coordinates

Coordinates are the numbers used to tell us how to get to a certain point on a grid - e.g a graph or a map. this grid will have an x axis whioch runs horizontally, and a y axis that runs vertically.

Coordinates are written in pairs. The coordinates of P on the graph above is (2,1). the first number in the pair is known as the x coordinate (2,1).

The **x** coordinate tells us how many units to go across (to the **left** if it is a **negative** number, or the **right** if it is **positive**).

The **y** coordinate tells us how many units to go **up** if the number is…
