Coordinate Planes Review

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 ordered pairs?

Back

Ordered pairs are pairs of numbers used to represent the position of a point on a coordinate plane, written in the form (x, y). The first number represents the x-coordinate, and the second number represents the y-coordinate.

Front

What does the x-axis represent?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero. It is used to measure horizontal distances.

Front

What does the y-axis represent?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero. It is used to measure vertical distances.

Front

How do you find the coordinates of a point?

Back

To find the coordinates of a point, identify its horizontal (x) and vertical (y) distances from the origin (0,0) and write them as an ordered pair (x, y).

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 coordinates (0, 0).

Front

If you move right on the coordinate plane, what happens to the x-coordinate?

Back

If you move right on the coordinate plane, the x-coordinate increases.

Front

If you move left on the coordinate plane, what happens to the x-coordinate?

Back

If you move left on the coordinate plane, the x-coordinate decreases.

Front

If you move up on the coordinate plane, what happens to the y-coordinate?

Back

If you move up on the coordinate plane, the y-coordinate increases.

Front

If you move down on the coordinate plane, what happens to the y-coordinate?

Back

If you move down on the coordinate plane, the y-coordinate decreases.
