Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a two-dimensional space, typically written in the form (x, y), where 'x' is the horizontal coordinate and 'y' is the vertical coordinate.

Front

What does the x-axis represent in a coordinate plane?

Back

The x-axis represents the horizontal line in a coordinate plane, where the value of 'y' is zero.

Front

What does the y-axis represent in a coordinate plane?

Back

The y-axis represents the vertical line in a coordinate plane, where the value of 'x' is zero.

Front

Where is the origin located in a coordinate plane?

Back

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

Front

How do you identify the coordinates of a point on a graph?

Back

The coordinates of a point are identified by its position relative to the x-axis and y-axis, expressed as (x, y).

Front

What is the significance of the first number in an ordered pair?

Back

The first number in an ordered pair represents the x-coordinate, indicating the horizontal position of the point.

Front

What is the significance of the second number in an ordered pair?

Back

The second number in an ordered pair represents the y-coordinate, indicating the vertical position of the point.

Front

How can you determine if a point lies inside a triangle on a coordinate plane?

Back

To determine if a point lies inside a triangle, you can use methods such as the area method or checking the signs of the areas formed by the point and the triangle's vertices.

Front

What is the ordered pair for the point located at (3, 8)?

Back

The ordered pair for the point located at (3, 8) is simply (3, 8).

Front

If a point has coordinates (8, 2), where is it located in relation to the axes?

Back

The point (8, 2) is located 8 units to the right of the y-axis and 2 units above the x-axis.
