Exploring Rational Expressions: Addition and Subtraction Techniques

What is the primary purpose of a coordinate plane in mathematics?

• To plot algebraic equations

• To display data in a structured format

• To organize geographical maps

• To write and solve complex algorithms

What is the starting point called on a coordinate plane?

• Center

• Origin

• Axis

• Baseline

What is the significance of the origin in a coordinate plane?

• It is where both axes have the value zero

• It is the highest point on the plane

• It is only used in three-dimensional graphs

• It represents the maximum values of x and y

Which axis is horizontal on a coordinate plane?

• y-axis

• z-axis

• x-axis

• b-axis

What does the y-axis typically represent in a coordinate plane?

• Circular movement

• Diagonal movement

• Horizontal movement

• Vertical movement

What does the first number in an ordered pair represent?

• Position on the x-axis

• None of the above

• Position on the z-axis

• Position on the y-axis

How do you determine the position on the coordinate plane using ordered pairs?

• Use the first number for the x-axis and the second for the y-axis

• Add both numbers of the pair

• Use the first number for the y-axis

• Use the second number for the x-axis

If an ordered pair is (7, 6), what is the position on the y-axis?

• 1

• 0

• 6

• 7

If a point on a coordinate plane is (3, 2), what does '3' indicate?

• Distance from the origin along the y-axis

• Distance from the origin along the x-axis

• The angle from the horizontal

• The radius from the origin

What is the correct ordered pair notation for a point located at 10 on the x-axis and 10 on the y-axis?

• (1, 1)

• (0, 10)

• (10, 0)

• (10, 10)
