"y" is directly proportional to "x" if if there is a constant k ≠ 0 such that y = kx.
~~~~~~~~~~
- 68 = k * 5
5k = - 68
k = - 68/5 = - 11.6
~~~~~~~~~~
- 68 = k * 5
5k = - 68
k = - 68/5 = - 11.6

Bridget, you did not write any information about second "y" or "x" . Bellow is a copy of the problem you posted:
Suppose that y is directly proportionally to x and that y = -68 when x=5.
Question one is find the constant of proportionally to k.
K=
Then solve the problem
