Question

Bianca makes an initial deposit to open a savings account. She then makes monthly deposits of equal amounts. The balance in her account is given by the function equation B = 150 + 80d, where B is her account balance and d is the number of monthly deposits she makes.

What is the meaning of the slope in this equation?





A.


Bianca deposits $80/month.


B.


Bianca deposits $150/month.


C.


Bianca makes an initial deposit of $80.


D.


Bianca makes an initial deposit of $150.

Answer 1

The answer would be a. The initial value (y-intercept) is $150 and then she puts $80 in every month, another way to write the equation is B=80d+150
