-- 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.
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
It is the Slope-Intercept Form of a linear equation. y=y-value x=x-value m=slope of the line b=y-intercept thx 4 the answer
Since there is no equation given, there can be no answer to the question.
Let's assume (for simplicity) that "y" is a function of "x". That means that for every value of "x", there is a unique value of "y". In this case, if the equation can be solved for "y", it is a function. Some equations are difficult or impossible to solve explicitly for "y"; in this case, "y" may still be a function of "x", if for every value of "x" only a single value of "y" is possible for the equation. However, if this is the case, it may be difficult to verify.
y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
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
Without an equality sign it is not an equation and so therefore its value can't be determined.
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.
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.
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
-- 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.
