If we want to graph a horizontal line, we will do the following:

$y=0x+3$

No matter the domain for x, the range for y will always be 3. Therefore, we have a horizontal line.

$y=0\left(0\right)+3=(0,3)$

$y=0\left(1\right)+3=(1,3)$

$y=0\left(2\right)+3=(2,3)$

Now the formula to graph a vertical line looks like this:

$x=3$

Well, wait a second. Where is the y? I would like to see the y in the equation. But it is missing. How can I write the equation for a vertical line that includes the y variable? This is all I can think of:

$x=0y+3$

And with the following domain:

$x=0\left(0\right)+3$

$x=0\left(1\right)+3$

$x=0\left(2\right)+3$ Is this correct? Is it ok to reverse the x and y, as I just did above? Or does this not make it a slope-intercept equation anymore? It should still be a linear equation, since the variables are raised to the first power, in my opinion. But the slope-intercept form looks like this: y = mx + b. So I am not sure if this is still a slope-intercept equation.

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$\mathbb{F}}^{n}\mapsto {\mathbb{F}}^{m$
