There's no way to answer that with the information given.
' Y ' might be -0.4x . Then, when ' x ' is 5, ' y ' is -2 .
OR, ' y ' could be x-14. Then, when ' x ' is 5, ' y ' is -9 .
There's just not enough given information to know.

We cannot determine y when x = 5 since we only have one data point (10, -4) and no clear relationship. Without more information, y could be any value. Thus, we need more data points to find a specific answer.
