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.
If you mean: y = 2x+5 then yes it is a linear function of straight line

If you mean: y = 2x+5 then it is a straight line equation.
The y value will equal 15, when x = 7
Thanks to the browser, it is not possible to tell what the inequalities are.

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
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.
If you mean: y = 2x+5 then it is a straight line equation.
Unfortunately, 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. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals". In any case, this site is no good for seeking answers in graph form.

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.
Thanks to the browser, it is not possible to tell what the inequalities are.
If you mean: y = 2x+8 then it is a straight line equation whereas 2 is the slope and 8 is the y intercept
If y is equal to 2x, the graph would be a straight line going through the origin. The line would go up and to the right, and the angle at the origin has a tangent equal to 2. This angle is between 63 and 64 degrees.
