identify the coefficients in the expression below.
-6x + 5y + 4x + 9
a. -6,5,4,9
b. -6,5,4
c. 9
d. -6x, 4x

B. -6,5,4

Step-by-step explanation:

To find the coeffiecient in

-6x +5y + 4x + 9

we will first have to know what coefficients are.

Coefficients are constant quantitiy placed before a variable, this contant quantity must be placed in such a way that it is multiplying the variable.

So, from the above definition; we can deduct that -6 is placed before the variable x and it is multiplying x.

-6 is a coefficient of x.

5 is placed before the variable y and is multiplying y, then 5 is a coefficient of y.

4 is placed before the variable x and is multiplying x, then 4 is a co-efficient of x

But 9 is not attached to any variable, so 9 cannot be called a coefficient but rather 9 is just a CONSTANT.

Therefore the coefficients are; -6, 5 and 4
