Answer: None.
Step-by-step explanation:
None of these answer options are a linear function. I have plotted the coordinate points you shared since there is no image, see attached.
A linear function is graphed with a straight line and shown in the forms Ax + By = C, y = mx + b, or y - y1 = m(x - x1). None of these functions match this description.
While there is a straight line, option 1, this line is not a function. It does not pass the vertical line test because it has multiple outputs for one input.
