Question 778706
You can only do a linear fit if you have just two data pairs.

In form of (x, y) ordered pairs, your points are (100, 165) an (600, 195).


slope, {{{m=(195-165)/(600-100)}}}.

Pick either point and find vertical-line intercept from {{{y=mx+b}}}, as {{{b=y-mx}}}


y will be your cost function.
