So just like we did with demand, we're going to do the same thing with supply and thinking of shifts to the right as good things happening for supply and shifts to the left as bad things happening for the supply of our product, right? So when we have something good happen for the supply of the product, we are going to shift to the right. So an example of something good that could happen, what if the inputs, the things that we use to create the product, what if that gets cheaper? That's going to shift our supply line to the right. Cool. So that's a good thing for the supply. It'll shift to the right here and I just want to make this quick note right, if we have this price and this is our quantity we're at this price right here, p1, notice the price doesn't change but what happens at this price? Originally, we were going to be at this quantity right here, supplying this quantity, but now since whatever factor caused the supply to shift to the right, such as cheaper inputs, then at that same price, we're willing to create that much more quantity supplied, right? So notice we're keeping the price constant there, but the quantity supplied is increasing because the supply curve shifted. So just like that, let's do the opposite with the shifting left, right. This is when a bad thing happens to supply like the input price is going up, right. So we would shift to the left in this case and I'll draw a graph something like that, right, and we have effectively shifted to the left here. The same discussion there except now we would have a smaller quantity supplied at the same price. Cool, so this is how we're going to be shifting. Now let's learn about what are those factors that are going to be shifting our supply. Alright, let's do it.
