You can put this solution on YOUR website!
equation is 2x+y=5
\n" ); document.write( "to make y a function of x, you need to have y on the left side of the equation.
\n" ); document.write( "subtracting 2x from both sides of the equation gets
\n" ); document.write( "y = 5-2x
\n" ); document.write( "y is now a function of x.
\n" ); document.write( "y is the dependent variable because the value of y depends on the value of x.
\n" ); document.write( "x is the independent variable.
\n" ); document.write( "you can say y = 5-2x.
\n" ); document.write( "or you can say f(x) = 5-2x.
\n" ); document.write( "or you can say y = f(x) = 5-2x.
\n" ); document.write( "y is the dependent variable.
\n" ); document.write( "x is the independent variable.
\n" ); document.write( "f is the function name
\n" ); document.write( "you could call the function by any name.
\n" ); document.write( "if you said y = g(x), then g is the function name, and g(x) = 5-2x.
\n" ); document.write( "-----
\n" ); document.write( "as it stands, though.
\n" ); document.write( "y = f(x) = 5-2x would be the answer you are looking for.\r
