Identify the coefficients in the following expression.
-7x + 8y - 3z + y - 9

The coefficients are -7, 8, -3, 1, and -9

Coefficients are numerical quantity that are put before multiplying a variable in an expression, eg. 8 in 8x^y.
Therefore, the coefficients are:
-7
8
-3
and -9
Hope this helps!:)

I'm just guessing, but my answer would c. 0 to 300.
