Plot +C+ on the vertical axis
Plot +n+ on the horizontal axis
You are given the points
( 2,120 )
( 4,160 )
-------
+%28+C+-+120+%29+%2F+%28+n+-+2+%29+=+%28+160+-+120+%29+%2F+%28+4+-+2+%29+
+%28+C+-+120+%29+%2F+%28+n+-+2+%29+=+40+%2F+2+
+%28+C+-+120+%29+%2F+%28+n+-+2+%29+=+20+
+C+-+120+=+20%2A%28+n+-+2+%29+
+C+-+120+=+20n+-+40+
+C+=+20n+%2B+80+
-----------------
check:
Does the line go through ( 2,120) ?
+120+=+20%2A2+%2B+80+
+120+=+120+
Does the line go through (4,160) ?
+160+=+20%2A4+%2B+80+
+160+=+160+
OK
