Answer:
slope = -3
Step-by-step explanation:
This equation isthe form: y = mx + c
y= -3x-2
so, m = -3
This is false.
The f(3x) means you are multiplying the input 'x' by 3 before plugging into the equation.
3f(x) means you are going to multiply your answer (output) by 3 after you've plugged the input value in and gotten the output.
