4x - 2y = 12 divide by 2 both sides
2x - y = 6 subtract 2x to both sides
-y = -2x + 6 multiply by -1 to both sides
y = 2x - 6
Slope = m = 2, and y-intercept is -6.
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
It makes it easier to work out values for x and y for graph plotting purposes.
You add one side of each of the equations to form one side of the new equation. You add the other sides of the equations to form the other side. Subtraction is done similarly.
Straight line equations have two variables in the form of x and y

y=a(bx) is the standard form
Below boiling point of water, water gets changed from liquid form into vapour form. This is called as vaporization. Thus change of state is possible even below boiling point. An liquid can be changed into solid at its freezing point. This is also a change of state.

Equations are never parallel, but their graphs may be. -- Write both equations in "standard" form [ y = mx + b ] -- The graphs of the two equations are parallel if 'm' is the same number in both of them.
I looked all over the internet and could not find a parametric equation for this shape. You can look at the link below to find the regular cartesian equation. If you are good at parametric equations you could probably convert this into parametric form. I am not so good at parametric equations.
Ax+By=C
You need to interpret the words of the sentence into an algebraic form.
