Part (a)
Independent variable = age
Dependent variable = height
"depends on age" indicates that age is independent.
-----------------------------------
Part (b)
Independent variable = amount of sleep
Dependent variable = mood
The key word is "determines". The stuff before this word is the independent variable which affects the dependent variable.
-----------------------------------
Part (c)
Independent variable = time water has been running
dependent variable = amount of water in the tub
Time is usually the independent variable
-----------------------------------
Part (d)
Independent variable = speed
dependent variable = distance from home
-----------------------------------
Part (e)
Independent variable = amount of homework done
dependent variable = speed
This seems like an odd pairing of homework and speed. Could there be a typo? I noticed that part (f) is very similar
-----------------------------------
Part (f)
Independent variable = amount of hw that is assigned
dependent variable = amount of homework done
Like with part (a), the stuff before "depends" is the dependent variable

Answer:
D(9, 1)
Step-by-step explanation:
A being the midpoint means its coordinates satisfy ...
A = (E + D)/2
Solving for D, we find ...
D = 2A -E
= 2(4, 5) -(-1, 9) = (2·4 +1, 2·5 -9)
D = (9, 1)
