Which of the following gives all of the coefficients of the algebraic expression negative 2 x squared plus 17 minus 15 x plus 7 x y ?

The coefficients are the numerical factors attached to terms containing variables. In −2x², −15x, and 7xy, the coefficients are −2, −15, and 7. The 17 is a constant term, not a coefficient, so the correct choice is “negative 15, negative 2, 7.”
