Coordinate Graphing

Front

What is an ordered pair in coordinate graphing?

Back

An ordered pair is a pair of numbers used to represent 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

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

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

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

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How do you plot the point (3, 2) on a coordinate graph?

Back

Start at the origin (0, 0), move 3 units to the right (positive x-direction), and then move 2 units up (positive y-direction).

Front

What is the origin in a coordinate plane?

Back

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

Front

What is the difference between positive and negative coordinates?

Back

Positive coordinates indicate positions to the right (for x) or above (for y) the origin, while negative coordinates indicate positions to the left (for x) or below (for y) the origin.

Front

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

Back

The first number in an ordered pair is the x-coordinate, which indicates 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 is the y-coordinate, which indicates the vertical position of the point.

Front

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

Back

To identify the coordinates, find the point's position relative to the x-axis (horizontal) and y-axis (vertical) and write them as (x, y).

Front

What does it mean to move 'right' on a coordinate graph?

Back

Moving 'right' means increasing the x-coordinate value.
