Which point has coordinates

(

–

)

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

To find the point with coordinates

(

–

)

first identify the

-coordinate

and the

-coordinate.

–

-coordinate

Start at the origin.

The

-coordinate

is 2. Since the

-coordinate

is positive, count two units to the right.

The

-coordinate

–

Since the

-coordinate

is negative, count five units down.
