ok first u need to find the gradient of the line connecting the 2 points. This is the change in y over the change in x $\"%28y2-y1%29%2F%28x2-x1%29\"$ ... doing this u get $\"%286-2%29%2F%283-%28-5%29%29\"$ = $\"1%2F2\"$ .\r
\n" ); document.write( "\n" ); document.write( "using the formula $\"y-Y1=m%28x-x2%29\"$ , where m is the gradient, and y1 and x1 are from the coordinate (3,6)\r
\n" ); document.write( "\n" ); document.write( "you get (using only one pair of coordinates) $\"y-6=1%2F2%28x-3%29\"$ \r
\n" ); document.write( "\n" ); document.write( "which simplifies to give you: $\"2%28y-6%29=x-3\"$
\n" ); document.write( "This simplifies to give you: $\"2y=9%2Bx\"$ \n" ); document.write( "

\n" );
