Coordinate Plane-Test

Front

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), used to locate points using ordered pairs (x, y).

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

How do you reflect a point over the y-axis?

Back

Change the sign of the x-coordinate of the point (x, y) to get (-x, y).

Front

How do you reflect a point over the x-axis?

Back

Change the sign of the y-coordinate of the point (x, y) to get (x, -y).

Front

What is the distance formula in the coordinate plane?

Back

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

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

What are ordered pairs?

Back

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

Front

What does it mean for a point to be in Quadrant I?

Back

Both x and y coordinates are positive (x > 0, y > 0).

Front

What does it mean for a point to be in Quadrant II?

Back

The x-coordinate is negative and the y-coordinate is positive (x < 0, y > 0).
