let the three points be A(4,3) , B(2,0) , C(-18,-12)\r
\n" ); document.write( "\n" ); document.write( "The three points will lie on the same line if the slope of the line AB is same as that of BC\r
\n" ); document.write( "\n" ); document.write( "Using the formula to find the slope of the line between two points (x1,y1) and (x2,y2) = \"%28y1-y2%29%2F%28x1-x2%29\"\r
\n" ); document.write( "\n" ); document.write( "Slope of AB = \"%283-0%29%2F%284-2%29\" = 3/2
\n" ); document.write( "Slope pf BC = \"%280-%28-12%29%29%2F%282-%28-18%29%29\" = 12/20 =3/5 \r
\n" ); document.write( "\n" ); document.write( "Since the slopes are not equal , they do not lie on the same line.\r
\n" ); document.write( "
