A line passes through (1,-5) and (-3,7) write an equation for the line in point - slope form
\n" ); document.write( "-------------
\n" ); document.write( "m = diffy/diffx = 12/-4
\n" ); document.write( "m = -3
\n" ); document.write( "---------
\n" ); document.write( "y = mx + b
\n" ); document.write( "Use either point
\n" ); document.write( "-5 = -3 + b
\n" ); document.write( "b = -2
\n" ); document.write( "---------
\n" ); document.write( "y = -3x - 2
\n" ); document.write( "
\n" ); document.write( "
\n" );
