Answer: -0.5.
Step-by-step explanation:
The constant of variation k for the direct variation is given by:-

The given table:
x f( x )
0 0
2 -1
4 -2
7 -3.5
Then,

Hence, the constant of variation k for the direct variation is -0.5.
Answer:
it's not 100 or 102, just took the test and got them both wrong.

Unit rate is when you get the value for 1 of the variables. In this, we would want to get the value for t. We do
to find the t value. Now we do
to find the value of the missing t. T=6.
