Linear. If q is the number of quarters and D the dollars, D = 0.25·q, which is of the form D = m·q with constant slope m = 0.25 and intercept 0. The graph is a straight line through the origin, and the relationship is proportional (doubling q doubles D), so it satisfies the properties of a linear function.
