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 (x, y).

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to locate points on a coordinate plane, written in the form (x, y). The first number represents the position on the x-axis, and the second number represents the position on the y-axis.

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

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0). It is the starting point for plotting points.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

What is an input/output table?

Back

An input/output table is a chart that shows how each input (x-value) is related to an output (y-value) through a specific rule or function.

Front

What does it mean to 'run before you jump' when plotting?

Back

'Run before you jump' means to move horizontally (along the x-axis) to the correct x-coordinate before moving vertically (along the y-axis) to the correct y-coordinate.

Front

What is the rule for the input/output table: X divided by 3 = Y?

Back

This rule means that for every input value (X), the output value (Y) is obtained by dividing X by 3.

How do you identify a point on a coordinate plane?

Back

To identify a point, look for its ordered pair (x, y) and find the corresponding location by moving x units along the x-axis and y units along the y-axis.
