Construct a Coordinate System

a grid that makes it easy to locate points in a plane using an ordered pair of numbers

• first quadrant

• coordinate system

• brackets

• coordinate series

In an ordered pair the first number represents which axis?

• x

• y

• z

• w

The coordinates for the origin in the coordinate plane are________?

• (1,1)

• (0,0)

• (0,1)

• (1,0)

A pair of numbers used to locate a point on a coordinate grid

• origin

• ordered pair

• coordinate grid

• x-coordinate

The ​ (a)   is the intersection of the x- and y-axes in a coordinate plane. The coordinated are (0,0)

• Origin

• Ordered Pair

• Domain

• Range

Given PQRS with P (3, 1), Q (8, 1), R (10, 4), and S (5, 4). If the diagonals intersect at point T, what are the coordinates of point T?

T = _​ (a)  

• (6.5, 2.5)

• (5, -3)

• (7, 3)

• (5.5, 1)

• (7.5, 4)

the first number in an ordered pair which names the distance to the right or left from the origin along the x-axis

• y-coordinate

• first quadrant

• coordinate grid

• x-coordinate

Ordered pair (0,0) is also known as the ___.

• y-axis

• x-axis

• origin

• I love Math!

The point where the two axes of a coordinate plane intersect. It is represented by the ordered pair (0,0).

• Coordinate system

• origin

• coordinate plane

• first quadrant

the second number in an ordered pair which names the distance up or down from the origin along the y-axis

• x-coordinate

• y-coordinate

• x-axis

• y-axis
