If a company manufactures 20 widgets it cost $405, the cost of manufacturing 500 is $1125. Assume the cost C depends linearly on the number x of widgets manufactured.
express the cost n terms of the number of widgets manufactured

You have 2 points on the graph, so you can just take the generic equation for a line:
y = mx + c
and work out what m and c must be.
What specifically are you having trouble with?
Which numbers do I plug where?
m is the gradient of the line, i.e.
and c can be obtained by plugging in one of the points.
This can then be verified with the other point.
I got! Thank you
