If you mean: y = 2x+5 then it is a straight line equation.
If you mean: y = 2x+5 then yes it is a linear function of straight line
Thanks to the browser, it is not possible to tell what the inequalities are.

Without a second independent equation, it's not a 'system' yet.

y2x - just double the coordinate of y to get x. xy12 - i have no idea

Since there is no equality (or inequality) sign in the question, there is no equation or inequality) and therefore nothing which can be solved.
Without any equality signs the given expressions can't be considered to be equations so therefore there are no solutions.
