Diego made a graph of two quantities that he measured and said, “The points all lie on a line except one, which is a little bit above the line. This means that the quantities can’t be proportional.” Do you agree with Diego? a
Yes, because measured quantities in a proportional relationship must always produce a perfectly straight line on a graph.
b
No, because measured quantities can have error and sometimes that error can show up as a point that lies slightly outside of a straight line even though it is actually a proportional relationship.
