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

How do you identify the quadrant of a point?

Back

By looking at the signs of the x and y coordinates: (+,+) for Quadrant I, (-,+) for Quadrant II, (-,-) for Quadrant III, and (+,-) for Quadrant IV.

Front

What are negative coordinates?

Back

Coordinates where either the x or y value (or both) is less than zero, indicating a position to the left of the y-axis or below the x-axis.

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 midpoint formula?

Back

The midpoint M between two points (x1, y1) and (x2, y2) is M = ((x1 + x2)/2, (y1 + y2)/2).
