Which of the following graphs represents a linear function? (2 points)

coordinate plane with a graph drawn that passes through the points 2 comma negative 2 and 2 comma negative 1 and 2 comma 0

coordinate plane with a graph drawn that passes through the points negative 1 comma 0 and 0 comma negative 2 and 1 comma negative 4

coordinate plane with a graph that passes through the points negative 2 comma 0 and 0 comma negative 4 and 2 comma 0

coordinate plane with a graph that passes through the points negative 3 comma 0 and 0 comma negative 3 and 3 comma 0 and 0 comma 3

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.
