If you mean y = 12x -2 and y = 12x then both slopes will be parallel but with the changed function having its slope passing through the origin (0, 0)
The graph would be translated upwards by 2 units.
The graph is a region of the space on one side or another of the related function. If the inequality is strict then the related function itself is not part of the solution; otherwise it is.
Multiplying a function by -1 will make it a reflection of the original function across the x axis.
The straight line in the graph goes 'uphill' from left to right
A Bar Graph
The answer will depend on what was changed to what!
The graph would be translated upwards by 2 units.
It would be shifted down
It would be less steep.
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
It would be less steep
The graph is a region of the space on one side or another of the related function. If the inequality is strict then the related function itself is not part of the solution; otherwise it is.
It is a reflection of the original graph in the line y = x.
Multiplying a function by -1 will make it a reflection of the original function across the x axis.

y=x
If you mean y = x+5 changed to y = x+9 then the lines will be parallel to each other but with different y intercepts.
