y is out of your system is 3 days form when you last took it.
y=x+9 y'=1 x+9=0 x=-9 y=-9+9 y=0
There are y/7 weeks in y days.
6 times with a remainder of 9 or 6.75 times
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
3x-y=9 y=3x-9
y -3 = 9 y = 9+3 y = 12
y + 9
y - 9
-3
Answer: y= -1 Solution: 4 - 2 y = 7 y + 13 subtract 7 y from both sides: 4 - 2 y - 7 y = 7 y + 13 - 7 y 4 - 9 y = 13 subtract 4 form both sides: 4 - 4 - 9 y = 13 - 4 - 9 y = 9 now divide both sides by - 9: -9 y / - 9 = 9 /-9 y = -1
If you mean: x+y = -9 then y = -x-9 whereas the slope is -1 and the y intercept is -9
