#Definition of Equation: #Linear VS Non Linear Equation:-
   • Equation and Types of Equation:  

An equation is a mathematical statement that shows the equality of two expressions by using an equal sign (=). It usually contains numbers, variables, and mathematical operations.
Example:

2𝑥 + 3 = 7

Terms are the individual parts of an equation or expression that are separated by plus (+) or minus (−) signs. Each term may be a number, a variable, or a product of numbers and variables.
Example:
In
3𝑥 + 5𝑦 −7, the terms are 3x, 5y, and −7.
A linear equation is an equation in which the highest power of the variable is one. The graph of a linear equation is always a straight line.
General form:

𝑦 = 𝑚𝑥 + 𝑐

where
𝑚 is the slope and
𝑐 is the y-intercept.
Example:

2𝑥 + 3 = 7

A non-linear equation is an equation in which the variable has a power greater than one, or involves curves, products of variables, or roots. The graph of a non-linear equation is not a straight line.
Example:

𝑦 = 𝑥^2 +3𝑥 +1

In summary:

An equation shows equality

Terms are the parts of an equation

Linear equations form straight-line graphs

Non-linear equations form curved graphs
