Knowledge Check Question 17 For each equation, determine whether it shows a direct variation (that is, shows directly proportional variables). If it does, find the constant of variation and write it in simplest form. 미니 -2x + y = 1 x Direct variation Not direct variation Sy = 25x Direct variation k = Not direct variation I Don't Know Submit SC 5 4 6 7 8
