Without an equality sign it is not an equation and so therefore its value can't be determined.
A function is an equation (a relation) which has only one y-value for every x-value. If a single x-value has more than one y-value, the equation is no longer called a function.
You solve an equation containing y.
y=4
Y = 82x, the value of Y will be 82 times whatever value of x that is chosen
It is the value of the equation y = f(x) when x = 0.
y must have a value of 0 at the x-intercept.
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
To determine the value of y when x is 0, we need a specific equation or context relating x and y. Without that information, we cannot provide an exact value for y. If you have a particular equation in mind, please share it for a more accurate answer.
-- In the equation of the graph, set x=0. -- Solve the equation for 'y'. -- The value you get for 'y' when x=0 is the y-intercept.
In the equation x = 3, if x = 3, the equation is true, if x has any other value, it is not. The value of any other variable, such as y, is irrelevant. I would say that the answer is 0 because otherwise y is part of the equation which clearly it isnt.
The value of y in the equation y = mx + b when x = 0 Thus the y intercept = b,the value of y crossing (intercepting) the y axis at x = 0 For example in equation y = 3x +4 then y intercept is 4
