The value of y varies directly with the value of x, and y = –21 when x = 3.
Which equations represent the relationship between y and x?
Choose exactly two answers that are correct.
A. -7x = -21 <--------
B. y/x = -7 <-----------
C. x/y = 7
D. xy = -7
Translating x and y into -21 and 3 (to make it easier for you guys)
A. -7 x 3 = -21 <--------
B. -21/3 = -7 <-------
C. 3/-21 = 7
D. 3 x -21 = -7
