+3x+-+y+=+2+
You have to get this to look like the
slope intercept form which is:
+y+=+m%2Ax+%2B+b+
+m+=+slope+
+b+=+y-intercept+
------------------------------
+3x+-+y=+2+
Subtract +3x+ from both sides
+-y+=+-3x+%2B+2+
You want +y+ to be positive, so
multiply both sides by +-1+
+%28-1%29%2A%28-y%29+=+%28-1%29%2A%28-3x%29+%2B+%28-1%29%2A%282%29+
+y+=+3x+-+2+
--------------------
Here's a plot of the line:
