The answer you are looking for is Y = 2/3X - 5.
To find this, you must fill in the equation Y = MX + B, where Y = -1, M = 2/3, and X = 6. Filling in for those variables, you should get -1 = 2/3(6) + B. Now, you solve for B. Multiply 6 and 2/3 together, by putting 6 over 1 and multiplying straight across. 6 times 2 is 12 and 1 times 3 equals. This will give you 12/3, which simplified, is 4. Then, subtract 4 from both sides to get B = -5. Finally, fill in Y = MX + B, but this time only fill in M (2/3) and B (-5). This making Y = 2/3X - 5 the answer. Here's a graph to show this is the correct answer.
I hope this helps!
Let
be the number of minutes.
The first tank starts with 1500 liters, and loses 4 liters per minute, so after
minutes there will be
liters of water.
The second tank is filled at 6 liters per second, i.e.
liters per minute.
So, there will be
liters of water in the second tank after
minutes.
The two quantities will be equal when
so, approximately, after 3.3 minutes.
