What is represented by a shift to the right of the demand curve?

The demand curve shows the inverse relationship between the amount of a given product people will consume at a given price. Basically, the higher the price, the less people are willing to buy.

So the highest point on the curve (where people will buy the most) is at the lowest price. As the curve slopes downward, the price increases, and there is less people are willing to buy.

A Shift of the demand curve leftward is caused by a change in tastes, an increase in the price of a complementary good, a decrease in the price of a substitute good, lower income. etc.

*A CHANGE IN PRICE OF THE GOOD IS A SHIFT ALONG THE CURVE NOT A SHIFT OF THE CURVE*
