If you're trying to see which one is correct, plug in any ordered pair and try
-5 * 4 + 22 = 2
Correct so (4, 22) is the answer.
Answer:
Step-by-step explanation:
Line contains the points (4, 5) and (9, 7).

All you have to do is plug in the x and y values for each ordered pair into the left hand side of the equation and see if you get 15 = 15. If you do, the ordered pair is a solution; otherwise it is not a solution. For example, let's try (-2,-3); that is x = -2 and y = -3:
2x - 9y = 15
2(-2) - 9(-3) = 15
-4 - (-27) = 15
-4 + 27 = 15
23 = 15
This is obviously not true, so (-2,-3) is not a solution. Now you try it on each of the ordered pairs given in the problem statement.
To answer this, we need to use the equation for the volume of a cylinder:

Where:
'V' : Volume
'r' : radius
'h' : height
Now we plug in our values and solve:


V = <span>13571.68 cubic feet
</span>
∴Despite not being exactly what we got, the answer must be 'B'. It is the closest value to our solution without going over.
Hope this helps!
