y2x - just double the coordinate of y to get x. xy12 - i have no idea
If you mean y = 2x then it is a straight line equation
If you mean: y = 2x+5 then it is a straight line equation.
If you mean y = 2x-2 then it is a straight line equation whereas the slope is 2 and the y intercept is -2 and its coordinates would be plotted on the Cartesian plane.

If you mean: y = 2x+5 then yes it is a linear function of straight line
The equations ( y = 2x ) and ( y = 2x + 3 ) are similar in that they both represent linear functions with the same slope of 2, indicating that for every unit increase in ( x ), ( y ) increases by 2 units. They differ in their y-intercepts: the first equation has a y-intercept of 0, while the second has a y-intercept of 3, meaning the graph of the second equation is shifted upward by 3 units compared to the first.
If you mean: y = 2x-4 then it is equal to a straight line equation
No because it's not a simultaneous equation but some kind of algebraic expression
Without a second independent equation, it's not a 'system' yet.
If you mean y = 2x-3 then the parallel equation will have the same slope of 2 but with a different y intercept
If you mean: y = 2x-4 and (1, 5) then the parallel equation is y = 2x+3
As written this is not a graphable thing. I does not represent a graphable equation because there is no "=" sign. Whatever the equation might be, the x intercept is found by setting y=0, which leaves you with an equation for x, which is the intercept.
