    It's D. -7-3 = -10. 5-(-2) = 7.

    Take it in individual sections... y2-y1 is (-7-3) which is -10.

    x2-x1 is (5--2)... double negative is a positive, so 5+2, which is 7.

    So, -10/7 is the real question... Which is -1.4285714.

    Don't you just input the numbers into the correct variables of your equation? If so, it looks like this...

    1: (-7-3)/(5- -2)

    2: (-10)/(5+2)

    3: (-10)/(7)

    4: This equals to -1.428571429...

    Hope I solved it slow enough so you know how to solve it...

    its D, all you have to do is plug in the numbers....(-7-3)/(5+2)=

    -10/7

    (y2 - y1) / (x2 - x1) = a

    ((-7) - (3)) / ((5) - (-2)) = a

    -10 / 7 = a

    Your answer is -10/7. Or (d)

    -7-3 = -10

    5 - -2 = 7

    Therefore the answer is -10/7 or d.

    Wow...

    Just do (-7 - 3) / (5+2) which will give you answer D

    -_-
