You can put this solution on YOUR website!
you need to find the slope which is change in y over the change in x or rise/run\r
\n" ); document.write( "\n" ); document.write( "slope for points (-1,-6) and (4,8) is (8-(-6))/(4-(-1))=14/5\r
\n" ); document.write( "\n" ); document.write( "now standard equation for point slope is y-k=m(x-h) where m is the slope and (h,k) is any point on the line.
\n" ); document.write( "I will be using point (4,8)
\n" ); document.write( ":
\n" ); document.write( "y-8=(14/5)(x-4)
\n" ); document.write( ":
\n" ); document.write( "y-8=14/5(x)-56/5--->multiply all terms by 5
\n" ); document.write( ":
\n" ); document.write( "5y-40=14x-56--->write in standard form
\n" ); document.write( ":
\n" ); document.write( "\"14x-5y=16\" is the equation with points (-1,-6) and (4,8)\r
\n" ); document.write( "\n" ); document.write( "y=mx+b format would be y=(14/5)x-16/5
\n" ); document.write( " \n" ); document.write( "
\n" );
