If you mean: y = 2x+5 then it is a straight line equation.
No, f(x) = x + x^5 in not linear.
The linear equation x=5 or any other number is a vertical line. There are more than one possible answer for y. Therefore it is not a function.
Only if it's a function.
No, for two reasons. The first reason is that, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. The second reason is that the answers browser does not have graphic facilities.

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

No.
No, f(x) = x + x^5 in not linear.
No, f(x) = x + x^5 in not linear.
No, it is not.
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.

Assuming the domain is unbounded, the linear function continues to be a linear function to its end.
No. An exponential function is not linear. A very easy way to understand what is and what is not a linear function is in the word, "linear function." A linear function, when graphed, must form a straight line.P.S. The basic formula for any linear function is y=mx+b. No matter what number you put in for the m and b variables, you will always make a linear function.
