Coordinate Planes- Pre-Test

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to locate points using ordered pairs.

Front

What are the axes in a coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line. They intersect at the origin (0,0).

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0,0).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x,y).

Front

How do you identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair (x,y) and indicates the horizontal position.

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair (x,y) and indicates the vertical position.

Front

What direction do you move first when plotting a point?

Back

You move right or left along the x-axis first, then up or down along the y-axis.

Front

If the ordered pair is (3,4), what is the x-coordinate?

Back

The x-coordinate is 3.

Front

If the ordered pair is (3,4), what is the y-coordinate?

Back

The y-coordinate is 4.

Front

What does the point (0,5) represent on a coordinate plane?

Back

It represents a point that is 0 units along the x-axis and 5 units up along the y-axis.
