+-3x+%2B+8y+=+-9+
This is in the so-called " standard form "
You want to get this into the form:
+y+=+m%2Ax+%2B+b+ which is the " slope-intercept form "
+m+ = the slope of the straight line
+b+ = the y-intercept
--------------------------
+-3x+%2B+8y+=+-9+
Add +3x+ to both sides
+-3x+%2B+3x+%2B+8y+=+3x+-+9+
+8y+=+3x+-+9+
Divide both sides by +8+
+y+=+%283%2F8%29%2Ax+-+9%2F8+
-----------------------------
