the line containing 1,-3 and 3,y is perallel [sic] to the line containing 5,-6 and 9,y find the value of y
\n" ); document.write( "---------
\n" ); document.write( "If they're parallel, they have the same slope.
\n" ); document.write( "---
\n" ); document.write( "Slope, m, = diffy/diffx
\n" ); document.write( "==================
\n" ); document.write( "For (1,-3) and (3,y),
\n" ); document.write( "m = (-3-y)/1-3 = (y-3)/2
\n" ); document.write( "---------
\n" ); document.write( "For (5,-6) and (9,y),
\n" ); document.write( "m = (-6-y)/(5-9) = (y+6)/4
\n" ); document.write( "==============
\n" ); document.write( "*********** Use parentheses for the points.
\n" ); document.write( "=======================
\n" ); document.write( "So, (y-3)/2 = (y+6)/4
\n" ); document.write( "---
\n" ); document.write( "Solve for y.\r
