Point A shows that she is incorrect.
With functions, you can perform the "straight line test through each point. If the line goes through both points, you know it's not a function.

Step-by-step explanation:
Answer: F (False)
Step-by-step explanation:
Jointly variation has the following form:
y=kxz
Where k is a constant of propotionality.
Substitute values:
If y=16, x=4 and z=2, then k is:

If x=-8 and z=-3 the the value of y is:

Then the answer is FALSE.
