    Divide the difference in y values by the difference in x values. \(\dfrac{f(-4) - f(-5)}{-4 - (-5)} \) Read f(-4) and f(-5) off the graph.

    f(-4) would be the y value at x = -4

    So yes, they would be -4 and 0

    Plug those in to the equation mathstudent gave you, for the f(-4) and f(-5)

    so the answer is -4?

    Which should be -4/1 which I don't see in your options

    yeah, so what is the right answer out of my options?

    Well we should be able to do it with just the two points, but I don't know why the answer isn't there

    so I just guess and hope that the answer is right?

    I guess I would give the closest answer (-5), but I wouldn't like it.....

    It looks like f(-5) = 1, and f(-4) = -4 \(\dfrac{-4 - 1}{-4 - (-5)} = \dfrac{-5}{1} = -5\)

    oh, so the answer is -5?
