Coordinate Plane

Front

What is the coordinate plane?

Back

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

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

What is the x-axis?

Back

The horizontal number line in the coordinate plane where the y-coordinate is zero.

Front

What is the y-axis?

Back

The vertical number line in the coordinate plane where the x-coordinate is zero.

Front

What is the origin in the coordinate plane?

Back

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

Front

How do you identify the quadrant of a point?

Back

By looking at the signs of the x-coordinate and y-coordinate.

Front

What happens to the coordinates of a point when it is reflected over the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the distance between the points (3, -5) and (3, -8)?

Back

3 units.

Front

How do you find the coordinates of a point in Quadrant II?

Back

The x-coordinate is negative and the y-coordinate is positive.
