Question 72607 • GA-Algebra: Concepts and Connections A
A direct-variation line has the form y = kx. Since it passes through (5, 12), k = 12 ÷ 5 = 2.4, so points on the line must satisfy y = 2.4x. The points (0, 0), (2.5, 6), (7.5, 18), and (15, 36) satisfy this rule; (3, 10) and (12.5, 24) do not.
