y = -4x + 9

x = -3

Step 2: Evaluate

  1. Substitute in x [Equation]:                                                                                y = -4(-3) + 9
  2. Multiply:                                                                                                             y = 12 + 9
  3. Add:                                                                                                                   y = 21
y =21
-4x-3 =12
12+9=21
