For two main reasons.
The first reason is that, depending on the information that is available to you (two points, a point and slope, slope and intercept) one or the other form is easier to find.
The second reason is that different forms are "better" in different situations. The slope and intercept are parameters that have very obvious interpretations in 2-dimensional geometry. In 3-d, however, they don't make such obvious sense.
The general form: ax + by + cz = k where a, b, c and k are constants is a line in 3-dimensional space. It is easily converted to 2-d (just remove the z term) or extended to 4-dimensions (add a "dw" term where d is a constant and w another variable). Extension to 5 or more dimensions is done similarly.
Simultaneous equation
A system of linear equations is two or more simultaneous linear equations. In mathematics, a system of linear equations (or linear system) is a collection of linear equations involving the same set of variables.
The statement "A system of linear equations is a set of two or more equations with the same variables and the graph of each equation is a line" is true.
There are more than two methods, and of these, matrix inversion is probably the easiest for solving systems of linear equations in several unknowns.
Simultaneous equation is nothing: it cannot exist.A system of simultaneous equations is a set of 2 or more equations with a number of variables. A solution to the system is a set of values for the variables such that when the variables are replaced by these values, each one of the equations is true.The equations may be linear or of any mathematical form. There may by none, one or more - including infinitely many - solutions to a system of simultaneous equations.

A system of linear equations.
Linear Equations are equations with variable with power 1 for eg: 5x + 7 = 0 Simultaneous Equations are two equations with more than one variable so that solving them simultaneously
Normally no. But technically, it is possible if the two linear equations are identical.
we study linear equation in other to know more about quadratic equation
The statement "A system of linear equations is a set of two or more equations with the same variables and the graph of each equation is a line" is true.
Two or more linear equations are commonly referred to as a "system of linear equations." This system can involve two or more variables and is used to find the values that satisfy all equations simultaneously. Solutions to such systems can be found using various methods, including graphing, substitution, and elimination. If a solution exists, it can be unique, infinitely many, or none at all, depending on the relationships between the equations.
Depends if you enjoy Linear Equations or Trigonometry more. :)

The solution to a system on linear equations in nunknown variables are ordered n-tuples such that their values satisfy each of the equations in the system. There need not be a solution or there can be more than one solutions.
