Answer:
A
Step-by-step explanation:
First, put this equation in slope intercept form.
Where m is the slope and b is the y intercept.
Since it's greater than, the solution set is above the line, effectively eliminating graph D.
Now we should graph it.
We can see that the point 
is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.
Answer:
-14
Step-by-step explanation:
The volume of water that goes into the hose is the same as the volume of water that comes out the nozzle. This means the velocity is inversely proportional to the area. The area is proportional to the square of the diameter.
Taken together, these facts mean that if the diameter is divided by a factor of 3, the velocity is multiplied by a factor of 3^2 = 9.
Nozzle velocity = 3^2 * entering velocity
.. = 9 * (4 m/s)
Nozzle velocity = 36 m/s . . . . . . . . . corresponding to selection A
