Answer 2

I can’t see the graph image you mentioned. Please either upload the image or tell me the coordinates of a clear point on the line (a nonzero point), e.g. (volume in L, salt in g) — then I'll compute the unit rate.

How to find it yourself: pick any point (x, y) on the line (other than the origin). The unit rate = slope = y ÷ x (grams per liter). Enter that quotient as a decimal (no units).
