Get them all into the form
+y+=+mx+%2B+b+ where m = slope
(1) +5y+=+-3x+-+5+
(1) +y+=+-%283%2F5%29+-+1+
and
(2) +5y+=+-1+-+3x+
(2) +y+=+-%281%2F5%29+-+%283%2F5%29%2Ax+
and
(3) +3y+-+2x+=+-1+
(3) +3y+=+2x+-+1+
(3) +y+=+%282%2F3%29%2Ax+-+%281%2F3%29+
--------------------
The slopes are all different, so
no lines are parallel
