If the question was: y-2x = 18 then the y intercept is 18
If you mean y-6x = 18 then y = 6x+18 whereas 6 is the slope and 18 is the y intercept
y=1/3x x=-18 y=1/3(-18) y=-6
y < 18*6y < 18*6y < 18*6y < 18*6
You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
y-18=-3
x + y = 18, x - y = 6 y = 18 - x x - (18 - x) = 6 x - 18 + x = 6 2x - 18 = 6 2x = 24 x = 12 (12) + y = 18 y = 6
5y - 3y = 18 2y = 18 y = 18/2 y = 9
If Y is a variable, it can make the answer vary. If Y = 3, the LCM is 18. If Y = 5, the LCM is 90. If Y = 36, the LCM is 36. If Y is a question, the LCM of 2, 6 and 18 is 18 because 18 is the smallest positive integer that 2, 6 and 18 can all be divided into evenly with no remainder.
18• 6-y
5x-y equals 18 = -13
y varies directly as x y=kx, where k is a constant y=18 when x=3 18=3k k=6 y=6x
