A line contains the following points left to right: R, T, U, S. The space between R and T is 12 units. The space between R and S is 24 units. If TU = 6 units, what must be true?

SU + UT = RT
RT + TU = RS
RS + SU = RU
TU + US = RS

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
