Exploring Coordinate Grids Fundamentals

What is the primary purpose of using coordinate grids in geometry?

• To calculate angles between grid lines

• To plot points and understand spatial relationships

• To draw perfect circles

• To measure distances accurately

What does the first number in an ordered pair represent?

• The angle of elevation

• The x-coordinate

• The y-coordinate

• The distance from the origin

Where do all measurements on a coordinate grid begin?

• At the top left corner

• At the point called the origin

• At the y-axis

• At the x-axis

What shape is formed by connecting points (3,2), (7,2), and (7,8) on a coordinate grid?

• Circle

• Right triangle

• Square

• Rectangle

If a point is located at (0,5), where does it lie?

• At the origin

• None of the above

• On the x-axis

• On the y-axis

What ordered pair represents a point that is 9 units to the right and 4 units up from the origin?

• (9,4)

• (9,9)

• (4,9)

• (4,4)

How do you plot the point (1,0) on a coordinate grid?

• Move 1 unit up from the origin

• Stay at the origin and move 1 unit right

• Move 1 unit right and stay on the x-axis

• Move 1 unit right and 1 unit up

What is the correct ordered pair for a point that lies directly on the x-axis at 9 units from the origin?

• (9,0)

• (0,9)

• (9,9)

• (0,0)

Which ordered pair corresponds to a point that does not move horizontally from the origin but goes up 8 units?

• (0,8)

• (8,0)

• (0,0)

• (8,8)

If a point is plotted at (5,8), how many units right and up is it from the origin?

• 8 right, 5 up

• 5 right, 8 up

• 5 up, 8 right

• 8 up, 5 right
