Answer:
u = 7
Step-by-step explanation:
Using the slope intercept formula:

Substitute our values from the points and the known slope:

Now we multiply both sides by (8 - u) to isolate the x:
(8-u) x
= -7 (8 - u)
Next we add 56 to both sides:
-7 = -56 + 7u
Finish off by dividing both sides by 7:
7u = 49
u = 7
