Front

Name the ordered pair for point C.

Back

(3,4)

Front

In the ordered pair (4,9), which number is the x-coordinate?

Back

Front

How do you write an ordered pair?

Back

(x, y)

Front

What is the origin in the coordinate plane?

Back

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

Front

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

Back

The horizontal position of a point on the coordinate plane.

Front

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

Back

The vertical position of a point on the coordinate plane.

Front

How do you identify the quadrant of a point (x, y)?

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

Back

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