coordinate pairs

Front

What is a coordinate pair?

Back

A coordinate pair is a set of two numbers that define a point's position on a Cartesian plane, typically written in the form (x, y).

Front

What does the first number in a coordinate pair represent?

Back

The first number (x) represents the horizontal position of the point on the Cartesian plane.

Front

What does the second number in a coordinate pair represent?

Back

The second number (y) represents the vertical position of the point on the Cartesian plane.

Front

What is the origin in a coordinate system?

Back

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

Front

In which quadrant is the point (3, 4) located?

Back

Quadrant I, where both x and y are positive.

Front

In which quadrant is the point (-3, 4) located?

Back

Quadrant II, where x is negative and y is positive.

Front

In which quadrant is the point (-3, -4) located?

Back

Quadrant III, where both x and y are negative.

Front

In which quadrant is the point (3, -4) located?

Back

Quadrant IV, where x is positive and y is negative.

Front

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

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

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

Back

The midpoint formula is M = ((x1 + x2)/2, (y1 + y2)/2).
