Yes, ( y ) is proportional to ( x^2 ) if there exists a constant ( k ) such that ( y = kx^2 ). This means that as ( x ) changes, ( y ) changes in a way that is proportional to the square of ( x ). If you double ( x ), ( y ) will increase by a factor of four, illustrating the quadratic relationship.
The expression ( y2x + (-3) ) simplifies to ( y2x - 3 ). Here, ( y2x ) represents the term involving the variables ( y ) and ( x ), while ( -3 ) is a constant. Thus, the overall expression combines a variable term and a constant.
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.
If you mean: y = 2x-10 then it is 2x-y-10 = 0

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

y2x is an expression, which cannot be graphed because we don't know what it equals. y = 2x, y2 = x, and 2y (or y2) = x are all things that could actually be graphed.
It is an expression in two variables, x and y.

If you mean y = 2x then it is a straight line equation
Proportional is when it is proportional.
If you mean: y = 2x-4 then it is equal to a straight line equation
