The number that is multiplied to a variable.
the coefficient of the expression is 1 the coeffficient of the variable is 5
'y' is a variable. '15' is not. [ y+15 ] is an expression in one variable.
Often the x variable is the independent variable and the y variable depends on x.
the name for x variable is indepent name for y variable is depent
the variable is Y
"If y=2x, then x is the independent variable and y is the dependent variable." Also, " If x=y/2 then y is the independent variable and x is the dependent variable". Also, "The dependent variable is the one variable which is found by giving values to all the independent variables"
In the expression y+15, there is one variable, the "y."
It is called the independent variable. For example if you are trying to find y: y = x+1 X is the independent variable, and Y is the dependent variable. The value of Y, depends on the value of X.
If x causes changes in y, for example 23x3 =y then x is the independent variable and y is the dependent variable.
solve x=yz for the variable y
The y-axis is the metric of the dependent variable.
