hope it helps

Answer 2

To find the coefficient of a term in x (or any other variable), isolate the term in x and write it as multiplication and the real number involved in the multiplication is the coefficient of the term.

expression   term in x         write as a multiplication        find coefficient

 2x - 7                 2x                            2×x                                                       2

 x/2 - 10              x / 2                         (1/2)×x                                           1 / 2

- x + 7                 - x                             (-1)×x                                                - 1

x + 7                   x                                 (1)×x                                                1

- x/4                - x / 4                              (-1/4)×x                                        - 1 / 4

I hope this helps :)
