2x+y=5\r
\n" ); document.write( "\n" ); document.write( "Make y a function of x\r
\n" ); document.write( "\n" ); document.write( "To make y as a function of x means to make y depend on x.\r
\n" ); document.write( "\n" ); document.write( "To do so, isolate y. The goal is to place y alone on one side of the equation.\r
\n" ); document.write( "\n" ); document.write( "2x + y = 5\r
\n" ); document.write( "\n" ); document.write( "Subtract 2x from both sides.\r
\n" ); document.write( "\n" ); document.write( "y = -2x + 5....This is your answer.\r
\n" ); document.write( "\n" ); document.write( "In the equation, y = -2x + 5, the value of y depends on the value(s) you select for x.\r
\n" ); document.write( "\n" ); document.write( "This is why it's called \"y as a function of x.\"\r
\n" ); document.write( "\n" ); document.write( "Since, y = f(x), we can also write your answer this way:\r
\n" ); document.write( "\n" ); document.write( "f(x) = -2x + 5\r
\n" ); document.write( "\n" ); document.write( "I am sure that your teacher wanted the answer to be y = -2x + 5.\r
\n" ); document.write( "\n" ); document.write( "I hope this helps.\r
