The demand / supply graph is designed to have supply on the vertical axis (Y) and demand on the horizontal (X). Thus you will have a higher supply = lower demand, or lower supply = high demand.
supply must shift up/left because at every quantity, the price would be higher
The supply and demand curve follows four basic laws :If demand increases (demand curve shifts to the right) and supply remains unchanged, a shortage occurs, leading to a higher equilibrium price.If demand decreases (demand curve shifts to the left) and supply remains unchanged, a surplus occurs, leading to a lower equilibrium price.If demand remains unchanged and supply increases (supply curve shifts to the right), a surplus occurs, leading to a lower equilibrium price.If demand remains unchanged and supply decreases (supply curve shifts to the left), a shortage occurs, leading to a higher equilibrium price.
Change in demand.

Price will increase, quantity will decrease

Change in demand.
It is a shift of the demand curve to the right (an increase in demand) or to the left (a decrease in demand).

Shift of the curve to the left.
If OPEC reduced output, then world supply will fall. Thus, as supply falls, the price will rise, and the profits of oil-producing countries increase. (In a demand-and-supply graph, the supply curve will shift to the left and you'll see the change in price.)

Imagine the curves. A decrease in demand would lower the equilibrium price by moving the demand curve to the left, dragging the intersection point down.
