NS.6 Coordinate Plane

Front

What is the coordinate plane?

Back

The coordinate plane is a two-dimensional surface formed by the intersection of a horizontal number line (X-axis) and a vertical number line (Y-axis).

Front

What are the four quadrants of the coordinate plane?

Back

The four quadrants are: Quadrant I (top right), Quadrant II (top left), Quadrant III (bottom left), and Quadrant IV (bottom right).

Front

In which quadrant do both X and Y coordinates have positive values?

Back

Quadrant I.

Front

In which quadrant does the X coordinate have a negative value and the Y coordinate have a positive value?

Back

Quadrant II.

Front

What does the X coordinate indicate in a point (X, Y)?

Back

The X coordinate indicates the horizontal position, telling us to move left or right.

Front

What does the Y coordinate indicate in a point (X, Y)?

Back

The Y coordinate indicates the vertical position, telling us to move up or down.

Front

What is the horizontal number line in the coordinate plane called?

Back

The X-axis.

Front

What is the vertical number line in the coordinate plane called?

Back

The Y-axis.

Front

What happens to points in the graph when they are reflected across the X-axis?

Back

The Y coordinates of the points change sign, while the X coordinates remain the same.

Front

What is the origin in the coordinate plane?

Back

The origin is the point (0, 0) where the X-axis and Y-axis intersect.
