tate the function?
\n" ); document.write( "input x . . . . . -3 . . . . . 0 . . . . . 3 . . . . . . 6
\n" ); document.write( "output y. . . . . .1 .. . . . . . 0 . . . . . -1 . . . . .. -2
\n" ); document.write( "Notice as we move down 1 on the y, -1, then we move up 3, +3, on the x. Our slope is
\n" ); document.write( "m = rise / run = -1/3
\n" ); document.write( "We have a formula of
\n" ); document.write( "(i) $\"Y+=+%28-1%2F3%29x+%2B+b\"$
\n" ); document.write( "If x =0, then y = 0. So,
\n" ); document.write( "(ii) $\"0+=+%28-1%2F3%29%2A0+%2B+b\"$
\n" ); document.write( "(iii) $\"b+=+0\"$
\n" ); document.write( "The function is
\n" ); document.write( " $\"y+=+%28-1%2F3%29x\"$ \n" ); document.write( "

\n" );
