Answer:
well technically, there are two coefficients
the coefficient of (b^2) is 1 and the coefficient of b (itself) is -5.
But if you sre just looking for the coefficient ot just plain b, it is -5
Step-by-step explanation:
the reason I say the coefficient to (b^2) is 1 because if there is no number in front of the variable, it is automatcally assumed to be 1.
now, as for just plain b, it is -5 because the sign, positive or negative, before a number coefficient gets attached to that number. so, the entire term is -5b, which makes the coefficient to just plain b to be -5
