Answer:
C (–2, 1)
Step-by-step explanation:
It's C, because the question explained that the value of the input was -2. The input is the x coordinate and the output is the y coordinate. (x,y) (input,output).
Putting in the input, you get, (-2,y) ( y is the unknown y coordinate)
Since C is the only answer with -2 as the input, your answer is C
