    Answer:

    f(x) = -5x – 1.

    Step-by-step explanation:

    The y values are decreasing by 5 as the x values increase by 1, so it looks like a linear function.

    The slope = (4-9) / (-1 – (-2))  = -5  so we write:

    y = -5x + c where c is the y-intercept.

    When x = 0, c = -1  so the function is

    f(x) = -5x – 1.
