We need to know the schedules . . . How often does each shuttle run ?
Answer:
it is parallel to the y axis
The answer to number 3 is -12 because you would do X times 4 and then add 8
the answer to number 4 is 46 because you would do X times 3 and then add 7
Step-by-step explanation:
Let xy = k, where k is the constant of variation.
By using values of x and y in the table,
we see that (2)(48) = (4)(24) = (12)(8) = 96.
Hence k = 96, which is our answer.
Sadly, you didn't put any sums on your list of choices.
In fact, I can't even find a list of choices !
To find the distance between (7, -1) and (-8, -9),
you would build a sum under a square-root (radical)
symbol, and it would look something like this:
√ ( 225 + 64 ) .
