question

What is the

-coordinate

of the pink pentagon

-coordinate:

key idea

The coordinate plane is formed by a horizontal number line called the

-axis

and a vertical number line called the

-axis

Each axis crosses the other at 0. The point where the axes meet is called the

origin.

An ordered pair

(

)

describes the location of a point on the coordinate plane. The first number is called the

-coordinate

and the second number is called the

-coordinate

position along the

-axis

position along the

-axis

solution

Start at the pink pentagon

and move left until you reach the

-axis.

This position on the

-axis

is 1 unit above the origin.

So, the

-coordinate

of the pink pentagon

is 1.
