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.
A Bar Graph
line graph
A bar graph is best to compare the levels because you can have 6 different color bars connected on a graph to compare the lead contamination levels.

It would be less steep.
The answer will depend on what was changed to what!
It would be less steep
A bar graph would be the best graph or chart to use to compare and contrast information.

A Bar Graph
Both lines would be parallel to each but the y intercept would change from 5 to 9
It would be shifted down
line graph
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
