Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on the coordinate plane, written in the form (X,Y).

Front

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.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the Y-coordinate, which indicates the vertical position on the coordinate plane.

Front

How do you determine which quadrant an ordered pair is in?

Back

An ordered pair (X,Y) is in Quadrant I if both X and Y are positive, Quadrant II if X is negative and Y is positive, Quadrant III if both X and Y are negative, and Quadrant IV if X is positive and Y is negative.

Front

What are the coordinates of the origin on the coordinate plane?

Back

The coordinates of the origin are (0,0).

Front

How many quadrants are there in the coordinate plane?

Back

There are 4 quadrants in the coordinate plane.

Front

What is the Y-axis?

Back

The Y-axis is the vertical axis on the coordinate plane where the X-coordinate is 0.

Front

What is the X-axis?

Back

The X-axis is the horizontal axis on the coordinate plane where the Y-coordinate is 0.

Front

How do you calculate the distance between two points (X1,Y1) and (X2,Y2)?

Back

The distance can be calculated using the distance formula: D = √((X2 - X1)² + (Y2 - Y1)²).

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.
