Coordinates

Front

What is a coordinate?

Back

A coordinate is a set of values that show an exact position on a graph, usually represented as (x, y).

Front

What does the first number in a coordinate pair represent?

Back

The first number (x) represents the horizontal position on the graph.

Front

What does the second number in a coordinate pair represent?

Back

The second number (y) represents the vertical position on the graph.

Front

What is the origin in a coordinate system?

Back

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

Front

How do you identify a point on a graph?

Back

You identify a point by its coordinates, which tell you how far to move along the x-axis and y-axis.

Front

What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

The distance formula is √((x2 - x1)² + (y2 - y1)²).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, written in the form (x, y).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a graph where y = 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a graph where x = 0.

Front

How do you plot the point (3, 4) on a graph?

Back

Start at the origin (0, 0), move 3 units right (x-axis), then 4 units up (y-axis).
