A coordinate plane is an intersection of two number lines. Just like a regular number line, the ones on a coordinate plane could stretch on infinitely.

Questions and Answers
• 1.

### A coordinate plane, which is an intersection of how many number lines?

• A.

One

• B.

Two

• C.

Three

• D.

Four

Correct Answer
B. Two
Explanation
A coordinate plane is formed by the intersection of two number lines, one horizontal and one vertical. These number lines are called the x-axis and y-axis respectively. The x-axis represents the horizontal values or the values of the first coordinate, while the y-axis represents the vertical values or the values of the second coordinate. Therefore, the correct answer is two.

### The length of a coordinate plane's number lines is known as its ....

• A.

Scale

• B.

Axis

• C.

Quadrant

• D.

Value

Correct Answer
A. Scale
Explanation
The length of a coordinate plane's number lines is known as its scale. The scale determines the unit of measurement and helps in understanding the distance between points on the plane. It is used to accurately represent the values and positions of points in the coordinate system.

### By convention, we normally call the horizontal number line the ....

• A.

Y-axis

• B.

A-axis

• C.

X-axis

• D.

Z-axis

Correct Answer
C. X-axis
Explanation
The correct answer is x-axis because by convention, the horizontal number line is referred to as the x-axis. This is commonly used in coordinate systems to represent the horizontal position of a point. The x-axis is perpendicular to the y-axis, which represents the vertical position. The z-axis is typically used to represent the depth or height in a three-dimensional coordinate system.

### we normally call the vertical number line the ....

• A.

A-axis

• B.

X-axis

• C.

B-axis

• D.

Y-axis

Correct Answer
D. Y-axis
Explanation
The vertical number line is commonly referred to as the y-axis in mathematics. It is used to represent the values of the dependent variable in a coordinate system, while the horizontal number line is called the x-axis. The y-axis is perpendicular to the x-axis and helps in locating points in a two-dimensional plane.

### The axes cut the coordinate plane into how many equal sections or quadrants?

• A.

One

• B.

Two

• C.

Three

• D.

Four

Correct Answer
D. Four
Explanation
The axes of the coordinate plane, the x-axis and the y-axis, intersect at the origin and divide the plane into four equal sections or quadrants. Each quadrant is numbered from I to IV, starting from the top right and moving counterclockwise.

### The x-axis is also known as the ....

• A.

Horizontal line

• B.

Vertical line

• C.

Slant line

• D.

None

Correct Answer
A. Horizontal line
Explanation
The x-axis is also known as the horizontal line because it represents the horizontal or side-to-side direction on a graph. It is used to plot the independent variable or the variable being measured or observed in an experiment. The y-axis, on the other hand, represents the vertical or up-and-down direction. Together, the x-axis and y-axis create a coordinate system that allows for the graphical representation of data.

### The number line called the y-axis is known as ....

• A.

Horizontal

• B.

Vertical

• C.

Slant

• D.

None

Correct Answer
B. Vertical
Explanation
The y-axis on a number line represents the vertical direction. It is used to plot points and measure distances in the vertical plane. The y-axis is perpendicular to the x-axis, which represents the horizontal direction. Therefore, the correct answer is vertical.

### Coordinate Plane is a topic in which course?

• A.

Music

• B.

Sociology

• C.

Mathematics

• D.

French

Correct Answer
C. Mathematics
Explanation
The topic of the coordinate plane is a mathematical concept. It is a system used to locate points in a two-dimensional space using a pair of numbers called coordinates. This concept is widely taught in mathematics courses and is an essential foundation for understanding algebra, geometry, and other mathematical topics.

### Who is not a mathematician among them?

• A.

Pythagoras

• B.

Isaac Newton

• C.

Albert Einstein

• D.

Barack Obama

Correct Answer
D. Barack Obama
Explanation
Barack Obama is not a mathematician because he is known for his career in politics, specifically as the 44th President of the United States. Pythagoras, Isaac Newton, and Albert Einstein, on the other hand, are renowned mathematicians who have made significant contributions to the field of mathematics.

### Mathematics is usually taught at ....

• A.

School

• B.

Museum

• C.

Church

• D.

Mosque

Correct Answer
A. School
Explanation
Mathematics is usually taught at school because it is a fundamental subject that provides students with the necessary skills and knowledge to understand and apply mathematical concepts in various real-life situations. Schools have dedicated math teachers and curriculum that are designed to teach students different branches of mathematics, such as algebra, geometry, and calculus, at appropriate grade levels. Additionally, schools provide a structured learning environment where students can engage in math activities, practice problem-solving, and receive guidance and support from their teachers.
