Lesson

Let's remember how to read and plot positive coordinates in a coordinate plane.

Here is a number plane.

a

What object has coordinates (6,\,2)?

A

Star

B

Bike

C

Dog

D

Apple

Worked Solution

b

What are the coordinates of the rabbit?

Worked Solution

Idea summary

Important terms to remember for a coordinate plane:

axes - the horizontal and vertical lines, the x-axis and y-axis

quadrants - the four different sections our axes create

coordinates - these tell us where points are located, with an x-value and a y-value

origin - where both x and y are equal to 0 and it's where both axes meet

This video looks at all four quadrants of the coordinate plane.

What are the coordinates of the point shown in the coordinate plane?

Worked Solution

Plot the point (-9,\,3) on the coordinate plane.

Worked Solution

Idea summary

The coordinate plane has an x-axis which runs horizontally and a y-axis which runs vertically.

Each coordinate pair has an x-coordinate and a y-coordinate.

Introduce the Cartesian coordinate system using all four quadrants
