Understanding Ordered Pairs and Graphs

The video tutorial explains the concept of graphs and ordered pairs, highlighting their use in locating points on a grid. It covers the definition of coordinates, the origin, and how to find the coordinates of specific points (A, B, C, and D) on a graph. The lesson concludes with a prompt to work on exercises.

What is an ordered pair used for in the context of graphs?

• To describe the color of a graph

• To determine the size of a graph

• To calculate the area of a graph

• To locate a point on a graph

How are ordered pairs typically written?

• In square brackets separated by a semicolon

• In curly braces separated by a colon

• In parentheses separated by a comma

• In angle brackets separated by a dash

What are the coordinates of the origin on a graph?

• (0, 1)

• (2, 2)

• (0, 0)

• (1, 1)

Which axis is horizontal on a graph?

• The x-axis

• The w-axis

• The z-axis

• The y-axis

If a point is located at (4, 2), what does the '4' represent?

• The x-coordinate

• The distance from the origin

• The distance from the y-axis

• The y-coordinate

What is the x-coordinate of point B if it is two units to the left of the origin?

• 4

• 0

• -2

• 2

How do you determine the y-coordinate of a point located above the origin?

• By moving horizontally to the right

• By moving vertically down

• By moving vertically up

• By moving horizontally to the left

What is the significance of the order in an ordered pair?

• It determines the color of the point

• It affects the size of the graph

• It specifies the exact location of the point

• It changes the shape of the graph

What are the coordinates of point C if it is six units to the left and four units below the origin?

• (4, 6)

• (-6, -4)

• (6, 4)

• (-4, -6)

If point D is three units to the right and three units below the origin, what are its coordinates?

• (3, 3)

• (-3, -3)

• (3, -3)

• (-3, 3)
