24/yx there isn't an = sign
ZW is parallel to YX.
If you mean y = x+5 and y = x+9 then both slopes will be parallel but with different y intercepts
yx-3 is not an equation, and it has no graph.

There isn't any. " yx-1 " is not an equation.
When they are scalar, xy and yx are equivalent. When they are vectors or matrices, they are not equivalent.
Yes, xy is the same as yx, but should always be written as xy.
When you are multiplying the numbers. For example, yx multiplied by yz is equal to yx+z
If this means "what is x when 8x = 9x?" then there is no answer in this Universe. If you want common multiples of 8 & 9 then 72 and all its multiples. (8 & 9 are examples of xy and yx.)
If y = 0 then yx - 5 = 0*x - 5 = 0 - 5 = -5
