Lovely resource
There is a comment from 3 years ago saying that one of the slides is incorrect. This is still the case.
Unfortunately slide 3 is wrong. This graph does not represent inverse proportion. The variables in inverse proportion like the example next to the graph are linked by an equation y=k/x which is a reciprocal, also called rational graph.
Very useful with lots of good examples and practices. Nice and attractive slides too.
