With great difficulty because there is no equality sign and the plus or minus value of 7 is not given.
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-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.
You can graph an equation or an inequality but you cannot graph an expression.
y=7-3x
7
The y value will equal 15, when x = 7

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
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
