(I will include a picture in the attachment to help with the explanation)
Slope upward represent the increase in quantity as the price goes up.
As the price of a product is increased, the potential profit that the producer can generate is also higher. Because of this, they become motivated to supply more product for the customers. They will increase their production output and increase the amount of distributions to the market.
This is why the slope will become upward like the picture above.
