    The product of 2 and y means we multiply

    Nine less than that product means we subtract 9
    2y - 9

    Finally, the entire expression is not less than 15, which means 15 or more. We use greater than or equal to
    2y - 9 >= 15

    If you want to solve this inequality and write the interval notation, use our calculator.
