Question

2 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? explain.

Explanation:

If two quantities are proportional, their graph is a straight line passing through the origin. Even a single point not on the line (assuming measurement error is not extreme) disrupts the proportional relationship.

Answer:

No, I do not agree with Diego. For two quantities to be proportional, all points (including the origin) must lie on a straight line. Since one point is not on the line, the quantities are not proportional.
