    Hint: Slope means the increase in y when x is increased by 1. In the equation y=mx+b, m is the slope. If y increases when x increases, m is positive. If y decreases when x increases, m is negative. Read following link for more information: http://www.purplemath.com/modules/slope.htm

    I prefer you state the value of the choice, and not just the letter, in order to improve communication accuracy.

    If y decreases when x increases, m is negative that is what happened so i assumed that was the answer
