Without any equality sign and not knowing whether or not 2 is + or
I assume you mean...,12X - 5Y = 30Y = 2X - 6You are given Y, so insert it into the top equation above.12X - 5(2X - 6) = 3012X - 10X + 30 = 302X = 0X = 0=====so, obviously,Y = - 6======Check.12(0) - 5(- 6) = 3030 = 30========checks(0, - 6)=======Ordered pair.
If you mean: y = 2x+5 then it is a straight line equation.
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
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.

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-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

If you mean y = 2x-3 then it is a straight line equation whereas 2 is the slope and -3 is the y intercept
