Answer:
y = -1
Step-by-step explanation:
Any ordinate pair (x, y) represents the input output values of a function to be graphed.
For any input value of x, there will be an output value (y).
If input value for the graph attached is x = 0,
Output value will be represented by the y-value along y-axis as, y = -1
Therefore, y = -1 will be the answer.
