Step-by-step explanation:

Step 1: Define

N(y) = -3y - 7

N(1) is y = 1

Step 2: Evaluate

1. Substitute in y [Function]:                                                                               N(1) = -3(1) - 7
2. [Function] Multiply:                                                                                     N(1) = -3 - 7
3. [Function] Subtract:                                                                                         N(1) = -10
