recall:
\n" ); document.write( "A $\"linear\"$ function is a function whose graph produces a line. Linear functions can always be written in the form
\n" ); document.write( " $\"y=ax%2Bb\"$ or $\"y=b%2Bax\"$ ( they’re equivalent)
\n" ); document.write( "where $\"b\"$ is the $\"initial\"$ or starting $\"value\"$ of the function (when input $\"x=+0\"$ , it's y-intercept) and $\"a\"$ is the $\"constant\"$ $\"+rate+\"$ of $\"change\"$ of the function. \r
\n" ); document.write( "\n" ); document.write( "you are given:\r
\n" ); document.write( "\n" ); document.write( "rate of change $\"3\"$ which means $\"a=3\"$
\n" ); document.write( "and initial value $\"-1\"$ which means $\"b=-1\"$ \r
\n" ); document.write( "\n" ); document.write( "so, you have $\"y=3x-1\"$ \n" ); document.write( "

\n" );
