You missed the value of the slope and that information is needed.
Any way, I can show you how to calculate the answer given a generic value of the slope.
Assuming that the slope values m, you can use the formula:
m = rise / run = change in y / change in x
=> m = (n - 5) / (16 - 10)
=> n - 5 = m (16 - 10)
=> n - 5 = 6m
=> n = 6m + 5
Now I am going to calculate the value of n for several values of the slope (m):
m n = 6m + 5 answer
1/2 n = 6(0.5) + 5 = 8 the first option
-1/2 n = 6(-0.5) + 5 = 2 the second option
5/6 n = 6(5/6) + 5 = 10 the third option
11/6 n=6(11/6) + 5 = 16 the fourth option
1/6 n = 6(1/6) + 5 = 6 the fifth option
Now you have the procedure and the answer for several values of the slope, so you do not have problems to answer this question.
