[MACROECONOMICS] - Determining Equilibrium Interest Rate?

I need to find the equilibrium interest rate given:

Interest Rate%: $Money Demand
12 : 140
11: 160
10: 180
9: 200
8: 240
7: 300
6: 360
5: 440
4: 540

Assume Money Supply = 200


NOW for the question:

Money Supply = 120 .. what is the Equilibrium Interest Rate?


Some thoughts:
Obviously: Money Demand = Money Supply in equilibrium.
I graphed that shit out up there .. didn't really help me out.
I'm sure there's a multiplier that I can find that will help me but I'm not sure how to find it.
I'm being dumb and I should know this. I'm sure there's an algabraeic way of finding this.
I need to hand this shit in in 20 minutes. lol

Thanks for any help.. even if I don't finish this question in time at least I'll have the knowledge for next time.

    This looks pretty simple. You have a few points for money demand at given interest rates. Like you said at equilibrium money supply will equal money demand, so extrapolate the point where interest rate = money supply from all the points you listed. Looks like it would be around 13%. I don't think you can really get a neat algebraic equation from the points you've given
