Answer:An increase in demand and a decrease in supply
Explanation:The point of equilibrium is the meeting point of both demand and supply. in this case the demand curve shift rightward from the original demand curve DoDo to D1D1,the supply curve move leftward from SoSo to S1S1 .These changes in demand and supply curve will make equilibrium price to rise from P1 to P2 while equilibrium point moves from Eo to E1.
