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.
Select a set of values for x from its domain. Calculate the corresponding values of y using one of the given equations. Plot the points on the coordinate plane and join the points. Repeat for the second equation, to give a second line.
If you mean y = 2x then it is a straight line equation
y=2x+4 is in slope intercept form
If all the vertices and edges of a graph A are in graph B then graph A is a sub graph of B.
The y value will equal 15, when x = 7
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 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.
y2x - just double the coordinate of y to get x. xy12 - i have no idea

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.

It is an expression in two variables, x and y.
Select a set of values for x from its domain. Calculate the corresponding values of y using one of the given equations. Plot the points on the coordinate plane and join the points. Repeat for the second equation, to give a second line.
