Y over -6 > 10 and i need to solve

A. y < –16
B. y > –60
C. y > 4
D. y < –60 I got C, but that's not right

    y/-6 > 10
    y < -60

    Looks like D

    When you multiply be a negative value, change the direction of the inequality. It's just a shorthand way to make things switch sides. Since

    y/-6 > 10
    that's the same as
    -y/6 > 10
    add y/6 to both sides to get
    0 > 10 + y/6
    now subtract 10 to get
    -10 > y/6
    now multiply by 6 to get
    -60 > y
    or
    y < -60
