What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the coordinates of a point?

Back

A pair of numbers (x, y) that define the position of a point on the coordinate plane.

Front

What does the x-axis represent?

Back

The horizontal line in the coordinate plane where y = 0.

Front

What does the y-axis represent?

Back

The vertical line in the coordinate plane where x = 0.

Front

What are the four quadrants of the coordinate plane?

Back

Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

Where is the origin located?

Back

At the point (0, 0) where the x-axis and y-axis intersect.

Front

What is the significance of the point (0, 0)?

Back

It is called the origin and serves as the reference point for all other points on the coordinate plane.

Front

How do you identify the coordinates of a point?

Back

By moving horizontally to the x-value and vertically to the y-value from the origin.

Front

What is the distance between the points (2, 3) and (2, -1)?

Back

The distance is 4 units, calculated as |3 - (-1)|.

Front

What is the slope of a line?

Back

The ratio of the rise (change in y) to the run (change in x) between two points on the line.
