Coordinate Graphing

Front

What are the four quadrants in a 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

What is the definition of an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written as (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 are the coordinates for the origin in the coordinate plane?

Back

(0, 0)

Front

In the ordered pair (3, -2), what is the x-value?

Back

3

Front

In the ordered pair (-5, 4), what is the y-value?

Back

4

Front

How do you identify which quadrant a point is in?

Back

By looking at the signs of the x and y coordinates: (+,+) is Quadrant I, (-,+) is Quadrant II, (-,-) is Quadrant III, and (+,-) is Quadrant IV.

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

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

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
