In Linear Algebra Done Right, it defines the linear maps of a homogeneous system of linear equations with n variables and m equations as

$T({x}_{1},\dots ,{x}_{n})=(\sum _{k=1}^{n}{A}_{1,k}{x}_{k},\dots ,\sum _{k=1}^{n}{A}_{m,k}{x}_{k})=0$

My question is why the homogeneous system of linear equations can be expressed as the linear maps from$\mathbb{F}}^{n}\mapsto {\mathbb{F}}^{m$

General form of linear equation using two variables I always read can be written:

$Ax+By+c=0$

where A and B cannot both be 0.

So does it means like$1x+0y+c=0$

is a linear equation of two variables i.e basically what I am asking is that both A and B cannot be zero but can either A or B be 0 like:

$0x+4y-5=0$ or $3x+0y-15=0$

Are the above equation a Linear equation of 2 variables?

Is $y=20-b{x}^{2}$ a linear equation?

Linear equations are all equations where the highest degree of the expression is 1 but l want to know whether there are other forms of linear equations.

Consider$y=20-b{x}^{2}$ where y is a function of $x}^{2$ . Will this also be a linear equation even though it is a second degree expression? Does it make a difference if I say y is a function of $x}^{2$ instead of x.
