Coordinate Planes & Input / Output Tables

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to locate points using ordered pairs.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y), where x is the horizontal position and y is the vertical position.

Front

How do you read an ordered pair?

Back

The first number in an ordered pair represents the x-coordinate (horizontal position), and the second number represents the y-coordinate (vertical position).

Front

What does the point (0, 0) represent on a coordinate plane?

Back

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

Front

How do you move from one point to another on a coordinate plane?

Back

To move from one point to another, you can count the number of units to move left or right (x-direction) and up or down (y-direction).

Front

What is an input/output table?

Back

An input/output table is a tool used to show the relationship between input values (x) and output values (y) based on a specific rule or function.

Front

If the input is 3 and the output is 6, what is the relationship?

Back

The relationship could be that the output is double the input, represented by the function y = 2x.

Front

What does it mean if a point is in the first quadrant of a coordinate plane?

Back

In the first quadrant, both the x-coordinate and y-coordinate are positive.

Front

How do you find the distance between two points on a coordinate plane?

Back

You can use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the significance of the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate plane, while the y-axis is the vertical line. They help in locating points and graphing functions.
