goes through the origin, up and to the right
No translation will invert a quadratic graph.
The one which shows a straight line with a positive gradient of 3 and crossing the y axis at 2.
A linear equation ?
You find the equation of a graph by finding an equation with a graph.

The equation you have given, y + 2 = 7, does not describe a line, it describes the number 5. You would not graph a single number, there is nothing to graph.

No translation will invert a quadratic graph.
Goes from the origin to the North East (up and to the right).
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
This is a straight line graph with the equation, y = n where n is any positive or negative number.
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .

That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
The equation 0 equals 0 is an identity and contributes absolutely nothing to the part of the graph that you should shade or not. The tautological statement can be ignored.
