Counting on a Coordinate Plane

A grid that is formed when horizontal number lines intersect vertical number lines at their zero points is called

• ratio table

• coordinate plane

• graph

• ordered pair

The place where the x-axis and the y-axis intersect that their zero point (0,0) is called

• ratio table

• origin

• coordinate plane

• ordered pair

The horizontal number line on a coordinate plane is called

• y-axis

• coordinate plane

• x-axis

• ordered pair

A pair of numbers used to locate a point on a coordinate plane (x,y) is called

• origin

• x-axis

• y-axis

• ordered pair

Points A, B, C, D, and E form a pentagon. Write an ordered pair that can be located inside the pentagon.
