(4,80)
\n" ); document.write( "(12,160)
\n" ); document.write( ".
\n" ); document.write( "If we assign your two points as:
\n" ); document.write( "(x1,y1)=(4,80)
\n" ); document.write( "(x2,y2)=(12,160)
\n" ); document.write( "Then:
\n" ); document.write( "Slope = rise/run = (y2-y1)/(x2-x1)
\n" ); document.write( "plugging our numbers:
\n" ); document.write( "Slope = (160-80)/(12-4)
\n" ); document.write( "Slope = 80/8
\n" ); document.write( "Slope = 10
