Yes. A fraction is still a number after all.
Application: say you have y=(1/2)x+6, the slope is 1/2 so you start at 6 on the y-axis and go up one and over 2 and you have your next point (x=1). It's the same thing as saying the value of x is being divided by 2. If you can multiply x by a number, why can't you divide?
a more complex one would be y=(3/4)x+9 in which case, you're both multiplying and dividing. You're multiplying x by 3 and dividing that by 4.
An equation is linear when it contains only variables of degree 1 and constants. ALL linear equations will be of the form: a1x1+a2x2+a3x3+...+anxn=c where an and c are constants.
A linear equation, when graphed, is always a line. A quadratic is a curve. Also, linear equations are of the form y=mx+b where m and b are arbitrary constants and quadratics are y=(x^2) +mx +b where m and b are arbitrary constants.
y = 5x3 + 6 is a cubic equation, not a linear equation. Linear equations contain only terms of degree 0 (i.e. constants) and terms of degree 1.
Yes, linear equations can yield negative values depending on the values of the variables involved. For example, the equation (y = 2x - 5) can produce negative outputs for (x < 2.5). Additionally, the coefficients and constants in a linear equation can be negative, affecting the overall behavior of the equation. Thus, both the outputs and components of a linear equation can indeed be negative.
The method is the same.
One of the most common ways to represent linear equations is to use constants. You can also represent linear equations by drawing a graph.
An equation is linear when it contains only variables of degree 1 and constants. ALL linear equations will be of the form: a1x1+a2x2+a3x3+...+anxn=c where an and c are constants.
The method is exactly the same.
One linear equation: Ax + By = C (A, B, and C are constants) Another linear equation: Dx + Ey = F (D, E, and F are constants) Their sum: (A+D)x + (B+E)y = (C + F) The coefficients (A+D), (B+E), and (C+F) are still constants, so the sum is still a linear 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.

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.
The method is the same.
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
