Are you aware of how to find a function? It's kind of like a trial and error process.

(-5,22),(10,-23),(4,-5),(-7,28),(6,-11)

x = -5, 10, 4, -7, 6
y = 22, -23, -5, 28, -11.

The next phase is to put them in order (least > greatest).

-7, -5, 4, 6, 10
-23, -11, -5, 22, 28

Now, can you see any pattern? Comment back and let me know.
(As x increases, y increases by ?)

Answer 3

i cant see a pattern im so lost.

Answer 4

Take -7 and find the difference between it and -23.
Find the difference of -5 and -11.

For example, the difference between 10 and 28 is 18.

Answer 5

-30,-16,-1,-16, and -18

Answer 6

you might wanna redo that :/

Answer 7

i subtract right

Answer 8

When dealing with negaive numbers it's a bit different. You want to just count the numbers between.

Answer 9

16,6,1,16,18

Answer 10

Assuming it is linear
(4,-5) (6, -11)
slope =-6/2 =-3
y+5 =-3(x-4)
y+5 =-3x +12
y=-3x +7
it works for all the other points
