Answer

$(1,-9), (0,0), (2,-18)$

Work Step by Step

To find the missing value, we plug in the value that we are given into the given equation and solve. $(1, ?) \rightarrow y=-9(1) = -9 \rightarrow (1, -9)$ $(0, ?) \rightarrow y = -9(0) = 0 \rightarrow (0, 0)$ $(?, -18) \rightarrow -18 = -9(?) \rightarrow ? = \frac{-18}{-9} = 2 \rightarrow (2, -18)$
