    • Yes, in a direct variation equation (y = kx), the graph of the relationship must pass through the origin (0,0).
26. Is varies inversely the same as inversely proportional?
    • Yes, “varies inversely” and “inversely proportional” are often used interchangeably to describe the same type of mathematical relationship where one variable decreases as the other increases, and vice versa.
27. What is inversely vs directly related?
    • Inversely related means that as one variable increases, the other decreases proportionally, while directly related means that as one variable increases, the other increases proportionally.
