Then, y can be any value such that x = 0! If that equation doesn't contain y values, then this means that any y value work for the equation! For instance, if y = 1, then x = 0. If y = 2, then x = 0 and so on.
That is the value called the y intercept - value of y when x = 0 for example if y = 3x + 4 b = 4 and y = 4 when x = 0
if x:=x(y) then y=0 => x=x(0)
x + y + z = 0 x = a - b, y = b - c, z = c - a, therefore a - b + b - c + c - a = ? a - a + b - b + c - c = 0

y = 6
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
Then, y can be any value such that x = 0! If that equation doesn't contain y values, then this means that any y value work for the equation! For instance, if y = 1, then x = 0. If y = 2, then x = 0 and so on.
here for least value X=2,y=3hence 2(3)-3(2)=0=0
If Y = 0 then there is no value of X such that XY = 1.
y=|x|/4 The range is [0 , ∞ )
y=0. note. this is a very strange "curve". If y=0 then any value of x satisfies the equation, leading to a curve straight along the y axis. For any non-zero value of y the curve simplifies to y = -x. The curve is not differentiable at the origin.

x = y = 0 ?
It is the intercept: the value that y takes when x = 0
The y intercept is where x = 0 and the x intercept is where y = 0. Choosing a value of 0 for x in the given equation yields y = 5 for the y intercept; choosing a value of 0 for y in the given equation yields -2x = 5 or x = -5/2 for the x intercept.
