    Your answer to question #1 is correct.
    Did you attempt question #2? I'd like to compare answers.

    i plugged it into the slope formula (y2-y1/x2-x1)
    and thats 9.2--10/-10-9.2 but im not sure if its correct

    The question asked for the answer in degrees.
    hmmm..... I suppose the slope can be converted into degrees, but it has been 23 years since I've studied my trigonometric identities.

    I think it would be easier to just draw a triangle and figure out the angle using the proper trigonometric function based on whichever two sides you pick.
