I need to be able to graph these two equations on microsoft excel as a demand curve for economics

My teacher states this: plot Q = 2100 - 50P
(Q is on horizontal axis ranging from 0 to 3000, and P is on vertical axis, ranging from 0 to 60. Label this demand as D1

Also states that "our market has what is called a fixed supply, that is the sameamount is supplied at any price. This is Q = 1200. And will be labeled S1, what is the equilibrium price

Suppose that the demand now increases suddently to Q = 2700 - 50P, plot this demand and what is the equiplibrium?


I also need to plot Q = -600 +100P

Please help im extremely lost, if i can get these 3 plots Id very much appreciate it.
