Answer 1

I guess you have to try each choice. Two of them should "work"

Answer 2

ok let me try them

Answer 3

um so i replace the x's and y's with the coordinates?

Answer 4

I would replace the x with the first number in the ( x,y) pair
do the calculation, and see if the y I get matches the y in the answer

Answer 5

ok thank you um can you check my work then?

Answer 6

i think A is right

Answer 7

Here is the first choice (-9,4)
\[ y = \frac{4}{-9}\cdot -9 \\ y= \frac{4}{\cancel{-9} }\cdot \cancel{-9} \\y=4\]

Answer 8

yeah so A is right but B is not

Answer 9

C is also wrong

Answer 10

yes. Notice if you multiply by 9 it cancels the 9 in the bottom, so I would check D next
(I would expect it to work)
