Ordered Pairs: point distances

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you find the distance of a point from the x-axis?

Back

The distance of a point from the x-axis is equal to the absolute value of its y-coordinate.

Front

How do you find the distance of a point from the y-axis?

Back

The distance of a point from the y-axis is equal to the absolute value of its x-coordinate.

Front

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

Back

The distance is calculated using the formula: √((x2 - x1)² + (y2 - y1)²).

Front

What is the first quadrant in a coordinate plane?

Back

The first quadrant is the section of the coordinate plane where both x and y coordinates are positive.

Front

What is the significance of the coordinates (7, 8)?

Back

The coordinates (7, 8) represent a point that is 7 units to the right of the y-axis and 8 units above the x-axis.

Front

How do you determine which point is closer to another point?

Back

To determine which point is closer, calculate the distance from each point to the reference point using the distance formula.
