They are called simultaneous equations.
A system of linear equations.
A system of linear equations that has at least one solution is called consistent.
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.
Because, if plotted on a Cartesian plane, all solutions to the equation would lie on a straight line.
All linear equations are functions but not all functions are linear equations.
There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
It is a linear equation. The highest power of x in the equation is 1 (3x1-4=12) so its "degree" is 1, and equations of "degree 1" are called linear equations.
Linear equations are always functions.
