# How to Draw a Point from Cartesian Coordinates

## Drawing a Point from Cartesian Coordinates

A point can be drawn on a graph. The Cartesian coordinates of the point tell us where to draw the point on the graph.

Imagine you wanted to draw a point with Cartesian coordinates (2, 4).

## How to Draw a Point from Cartesian Coordinates

Drawing a point from Cartesian coordinates is easy.

Cartesian coordinates have 2 numbers. • The number on the left (2) is called the x-coordinate. It tells you how far across the point is (in the horizontal direction) by measuring how far along the x-axis it is.

• The number on the right (4) is called the y-coordinate. It tells you how far up the point is (in the vertical direction) by measuring how far up the y-axis it is.

### Question

Draw the point with Cartesian coordinates (2, 4) on a graph.

# 1 Don't forget: A graph has a pair of axes: the horizontal axis is called the x-axis and the vertical axis is called the y-axis. They meet at the origin.

# 2

Find the first number in the Cartesian coordinates (called the x-coordinate). In our example, the x-coordinate is 2.

(2, 4)

# 3

Starting from the origin, count along the x-axis until you find the x-coordinate found in Step 2 (2). # 4

Find the second number in the Cartesian coordinates (called the y-coordinate). In our example, the y-coordinate is 4.

(2, 4)

# 5

Count up the y-axis until you find the y-coordinate found in Step 4 (4). # 6
