## How to Read Off the Cartesian Coordinates a Point

Reading off the Cartesian coordinates of a point is easy.

### Question

What are the Cartesian coordinates of the point shown on the graph below.

### Step-by-Step:

# 1

Read off how far **across** the point is along the horizontal x-axis.

We see that the point is **2** units along the x-axis.

**2 is the x-coordinate of the point**.

**Note:** The x-axis is labelled with numbers (0, 1, 2, 3...) so you can measure how far across the point is.

# 2

Read off how far **up** the point is along the vertical y-axis.

We see that the point is **4** units up the y-axis.

**4 is the y-coordinate of the point**.

**Note:** The y-axis is labelled with numbers (0, 1, 2, 3...) so you can measure how far up the point is.

# 3

Write down the Cartesian coordinates as a pair of numbers in brackets, separated by a comma.

The x-coordinate (**2**) found in **Step 1** goes on the left.

The y-coordinate (**4**) found in **Step 2** goes on the right.
