Using Microsoft (MSFT) option prices:

Draw the individual and net profit/loss payoff diagrams for a bull spread based on the Dec 2017 82.50 and 85.00 calls (expiration 12/15/2017). First, graph the profit/loss payoff diagram for each of the two individual calls; second, then sum up the individual payoffs to get the net payoff and then graph it. You should have 3 superimposed plots all on a single graph: the graphs of the two individual call positions and the net payoff.

Given the strike price on 11/14/2017 of $84.05. How does the graphs will look like?
