What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, which indicates the horizontal position on the coordinate plane.

How do you identify a point on a coordinate plane?

Back

To identify a point on a coordinate plane, use its ordered pair (x, y) where x is the horizontal distance from the origin and y is the vertical distance.

What is the significance of negative coordinates?

Back

Negative coordinates indicate positions to the left of the origin (for x) or below the origin (for y) on the coordinate plane.

How do you plot the point (2, -3) on a coordinate plane?

Back

To plot (2, -3), move 2 units to the right and 3 units down from the origin.

What is the distance between the points (1, 2) and (1, -2)?

Back

The distance is 4 units, calculated as the difference in the y-coordinates: |2 - (-2)| = 4.

What is the relationship between ordered pairs and functions?

Back

In functions, each input (x-coordinate) is associated with exactly one output (y-coordinate), forming ordered pairs.
