Question

The numerical coefficient of -r​

Answer 1

Answer:

-1

Step-by-step explanation:

The coefficient of a letter simply means what number is in front of that letter

In this case we see that -r doesn't have a number in front of it

But we also know that if a letter has a coefficient of 1 or -1, many don't add it.

So the numerical coefficient of -r is -1.
