Coordinate plane/Distance

Front

What is the distance between two points with the same x-coordinate?

Back

The distance is the absolute difference between their y-coordinates.

Front

What are the coordinates of a point located 4 units left and 2 units down from the origin (0,0)?

Back

(-4, -2)

Front

What does a reflection over the x-axis do to a point (x, y)?

Back

It transforms the point to (x, -y).

Front

How do you identify the coordinates of a point in the coordinate plane?

Back

The coordinates are given as (x, y), where x is the horizontal position and y is the vertical position.

Front

What are the four regions on the coordinate plane called?

Back

Quadrants.

Front

What is the distance formula used to calculate the distance between two points (x1, y1) and (x2, y2)?

Back

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

Front

If point A is at (2, 7), what is its reflection over the y-axis?

Back

(-2, 7).

Front

What is the significance of the origin in the coordinate plane?

Back

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

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to represent points in the coordinate plane, written as (x, y).

Front

How many quadrants are there in the coordinate plane?

Back

There are four quadrants.
