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). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: 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 find the distance between two points on a coordinate plane?

Back

Use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What are the coordinates of the origin in a coordinate plane?

Back

The coordinates of the origin are (0, 0).

Front

If a point is located at (3, -2), in which quadrant is it located?

Back

The point (3, -2) is located in Quadrant IV.

Front

What is the x-coordinate of a point?

Back

The x-coordinate is the first number in an ordered pair that indicates the horizontal position of a point on the coordinate plane.

Front

What is the y-coordinate of a point?

Back

The y-coordinate is the second number in an ordered pair that indicates the vertical position of a point on the coordinate plane.

Front

What is the formula to find the midpoint between two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Front

What are the coordinates of the point that is 5 units up from (2, 3)?

Back

The coordinates are (2, 8).

Front

What is the distance between the points (1, 1) and (4, 5)?

Back

The distance is 5 units.
