Find the distance between the two parallel lines given by the equation: 5x-4y=22 and -75x=150-60y
\n" ); document.write( "----------------
\n" ); document.write( "5x-4y=22 --> y = (5/4)x - 11/2
\n" ); document.write( "-75x=150-60y --> y = (5/4)x + 5/2
\n" ); document.write( "------------
\n" ); document.write( "y = (5/4)x - 11/2
\n" ); document.write( "(0,-11/2) is a point
\n" ); document.write( "Perpendicular thru the point --> y = (-4/5)x - 11/2
\n" ); document.write( "-----
\n" ); document.write( "y = (-4/5)x - 11/2 = (5/4)x + 5/2
\n" ); document.write( "-16x - 110 = 25x + 50
\n" ); document.write( "x = -160/41
\n" ); document.write( "y = 640/205 - 11/2 = 256/82 - 451/82 = -195/82
\n" ); document.write( "Intersection at (-160/41,-195/82)
\n" ); document.write( "--------------
\n" ); document.write( "\"d%5E2+=+diffy%5E2+%2B+diffx%5E2\"\r
\n" ); document.write( "\n" ); document.write( "d =~ 4.95
