### Linear Equations and graph is a sub-topic of ....

• A.

Algebra

• B.

Indices

• C.

Ratio

• D.

Proportions

A. Algebra
Explanation
Linear Equations and graph is a sub-topic of algebra because it involves the study and manipulation of equations that represent straight lines on a graph. In algebra, linear equations are used to represent relationships between variables, and their graphs provide visual representations of these relationships. By analyzing the slope and intercept of the line, one can determine various properties and solutions of the equation. Therefore, linear equations and graphing are fundamental concepts within the broader field of algebra.

### Who is not a mathematician among them?

• A.

Pythagoras

• B.

Albert Eisntein

• C.

Will Smith

• D.

Isaac Newton

C. Will Smith
Explanation
Will Smith is not a mathematician because he is primarily known as an actor and rapper, not for his contributions or expertise in mathematics. On the other hand, Pythagoras, Albert Einstein, and Isaac Newton are all renowned mathematicians who have made significant contributions to the field.

### The slope of the line is known as the .....?

• A.

Point

• B.

Coordinate

• C.

Axis

• D.

Explanation
The slope of a line refers to the steepness or incline of the line. It is a measure of how much the y-coordinate changes for every unit increase in the x-coordinate. The term "gradient" is commonly used to describe the slope of a line in mathematics and physics. Therefore, the correct answer is "gradient".

### The slope of the line is known as the gradient and is represented by .... in the equation.

• A.

M

• B.

N

• C.

A

• D.

B

A. M
Explanation
The slope of a line, represented by the variable m, is a measure of how steep the line is. It determines the rate at which the line rises or falls as you move along the x-axis. In the equation of a line, the variable m is used to represent the slope, indicating that it is the correct answer.

### An equation whose solution is a straight line is ...

• A.

Linear equation

• B.

Inequalities

• C.

Intercept

• D.

Coordinate

A. Linear equation
Explanation
A linear equation is an equation that represents a straight line on a graph. The solutions to a linear equation are the values that make the equation true. Therefore, if an equation's solution is a straight line, it must be a linear equation.

### Variables, equations, functions, graphs, etc are all features of ....

• A.

Indices

• B.

Ratio

• C.

Algebra

• D.

Proportion

C. Algebra
Explanation
Variables, equations, functions, and graphs are all fundamental components of algebra. Algebra is a branch of mathematics that deals with symbols and the rules for manipulating those symbols to solve equations and analyze mathematical relationships. It involves the use of variables to represent unknown quantities, equations to express relationships between variables, functions to describe mathematical relationships, and graphs to visually represent those relationships. Therefore, algebra is the correct answer as it encompasses all the mentioned features.
