Respuesta :
First, False b/c 7.5 is not the constant because it multiplies by y ==> 7.5 is a coefficient
Second, False because -z/9, you can understand it as [tex] \frac{-1}{9}z [/tex]. So, 7.5 and -1/9 are the coefficient, not 7.5 and -9.
Third, False, because z and y suppose to be the variable, not x and y variable.
Last, True because they both have the term y multiplies by a coefficient.
