Well, isn't that a happy little question! When y equals 0, it means that the point is right on the x-axis. So, the value of x at that point is also 0. Just like painting, math can be a beautiful and peaceful experience when we take our time to understand it.

When y equals 0, x can take on any value. This is because x and y are independent variables, meaning the value of x is not dependent on the value of y in this case. Therefore, x can be any real number when y equals 0.
Well, darling, when y equals 0, x can be any number under the sun! It's like a blank canvas waiting for Picasso to come along and work their magic. So, in mathematical terms, x is undefined when y equals 0. But hey, let's not get too hung up on technicalities, the world is your oyster!
Oh, dude, when y equals 0, x can be any number! It's like a free-for-all, man. So, technically, x could be 0, 1, -10, or even a million. The possibilities are endless, like a buffet of numbers.
There's no way we can figure that out until you tell us how 'x' and 'y' are related
to each other. That kind of information is called an "equation".
if y is directly proportional to x and x=3 when y=12
what is the value of y when x=5.2?
Well, darling, if x equals 0 in the equation, then y can be whatever the heck you want it to be! When x is 0, y is undefined, honey. So, go ahead and pick a number, any number, and call it y. Just don't expect it to make much sense in the grand scheme of things.
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
