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!

I am pretty sure it is 39 but I am not exactly sure. You might want someone else to solve this too. I did 27*.45=12.15 then I did 12.15+27=39.15 then I rounded the answer to the nearest whole number.
I hope this helped you:)
