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.

Directly means when x goes up by 3 then y goes up by 3
it is represented by
y/x=k where k stay the same
so y=-21
x=3

the equation is -21/3=-7
k=-7

so k =-7

therfor
y/x=-7
then manipulate the equation
multiply boht sides by x
y=-7x
subsitute valuse for x and get values for y
 if (x,y)
(1,-7)
(2,-14)
(3,-21)

so posiible equationscould be
-7/1=-7
-14/2=-7
-21/3=-7
and so on
