I'm not sure if that's the correct method of finding that (it could be, I was just never shown that kind of method). What I did was multiply everything out, that way you have two numbers vs two equations. Then add those two numbers and turn that into scientific notation.
Y = -x +6
the -x is because the slope of the line goes down 1 over 1, and -x is the same as -1x
the +6 is for the y intercept, at (0,6)
