we have a gradient/slope formula:\r
\n" ); document.write( "\n" ); document.write( " $\"%28y2-y1%29%2F%28x2-x1%29\"$ \r
\n" ); document.write( "\n" ); document.write( "x1=-17.6 y1=4.1 x2=-17.1 y2=3.2\r
\n" ); document.write( "\n" ); document.write( "substituting into our formula:\r
\n" ); document.write( "\n" ); document.write( " $\"%283.2-4.1%29%2F%28-17.1-%28-17.6%29%29\"$ \r
\n" ); document.write( "\n" ); document.write( "two negatives make a positive:\r
\n" ); document.write( "\n" ); document.write( " $\"%283.2-4.1%29%2F%28-17.1%2B17.6%29%29\"$ \r
\n" ); document.write( "\n" ); document.write( "= $\"-0.9%2F0.5\"$ \r
\n" ); document.write( "\n" ); document.write( "=-1.8 \n" ); document.write( "
