What value of y in math?

Answer 1

Y is just a variable. It depends how it is used.

5y-15=30 well y=9

In a graph you have (X,Y) coordinates also know as an ordered pair.

Standard Form Ax + By = C where A and B are not both equal to zero, A, B, and C are integers whose greatest common factor is 1, and A is nonnegative (if zero, B must be positive). The standard form can be converted to the general form, but not always to all the other forms if A or B is zero.

Slope intercept form y= m x+b where m is the slope of the line and b is the y-intercept, which is the y-coordinate of the point where the line crosses the y axis.

Point Slope Form y-y1=m(x-x1) where m is the slope of the line and (x1,y1) is any point on the line.The point-slope form expresses the fact that the difference in the y coordinate between two points on a line (that is, y− y1) is proportional to the difference in the xcoordinate (that is, x − x1). The proportionality constant is m (the slope of the line).

Functions where y = f ( x ) this is for mapping data A function is a relation (usually an equation) in which no two ordered pairs have the same x-coordinate when graphed.

All depends on how the Y is being used and Y can be used many ways.
