Understanding Ordered Pairs and Coordinates

The video tutorial explains the use of coordinates in everyday life, focusing on Cartesian coordinates developed by Rene Descartes. It covers how to mark points on a graph using the x and y axes, introduces the concept of ordered pairs, and demonstrates plotting points with specific coordinates.

What is a common way we use coordinates in daily life?

• To determine speed

• To pinpoint locations on a map

• To calculate distances

• To measure time

Who is credited with developing the concept of Cartesian coordinates?

• Isaac Newton

• Albert Einstein

• Rene Descartes

• Galileo Galilei

In Cartesian coordinates, what does the horizontal direction represent?

• Y-axis

• Z-axis

• X-axis

• W-axis

What is the vertical direction called in Cartesian coordinates?

• Z-axis

• Y-axis

• X-axis

• W-axis

Where do the x-axis and y-axis intersect?

• At the point (1,1)

• At the origin

• At the point (0,1)

• At the point (1,0)

What is the first step in setting up a scale on the axes?

• Choose a unit of measurement

• Draw the axes

• Number each line starting at zero

• Label the axes

How are coordinates written in an ordered pair?

• With a semicolon between numbers

• In any order

• Horizontal distance first, then vertical

• Vertical distance first, then horizontal

What is the purpose of using parentheses or brackets in coordinates?

• To separate the numbers

• To indicate multiplication

• To denote a set

• To enclose the ordered pair

What is the order of numbers in an ordered pair?

• Any order

• Horizontal first, then vertical

• Vertical first, then horizontal

• Based on the quadrant

What is the term for a pair of numbers in a specific order?

• Coordinate pair

• Ordered pair

• Number pair

• Graph pair
