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-3 then it is a straight line equation whereas 2 is the slope and -3 is the y intercept
If you mean: y = 2x-3 then the slope is 2 and the y intercept is -3
No because it's not a simultaneous equation but some kind of algebraic expression
yx-3 is not an equation, and it has no graph.
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-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.
Move 3 over the right side of the equation so the equation would be x = -3. The graph of this would be a verticle line at x= -3

If you mean: y = 2x-4 and (1, 5) then the parallel equation is y = 2x+3
