To find y and x on a graph, you must count how many squares one dot intercepts the same line as the other dot (in this case it's three) and for the y axis you do the ssme thing; find out how many squares are between both dots between the point where they intercept each other but for this time, it's vertically (in this case it's 6)
If one doctor warns 3 out of 10 people who are not vaccinated will suffer from flu like symptoms then, that means 30% of the people who are not vaccinated will suffer from flu symptoms. So in a study of 1 million unvaccinated inhabitants we would take 30% of 1 million which is 300,000. If 12,000 unvaccinated people suffer from the flu that means the amount of people who were unvaccinated and also do not experience the flu like symptoms would be I believe 70% of 12,000 which is 8400
