Raina is putting money into a checking account. Let $y$ represent the total amount of money in the account (in dollars). Let $x$ represent the number of weeks Raina has been adding money. Suppose that $x$ and $y$ are related by the equation $y=50 x+450$.
Answer the questions below.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.
What was the starting amount of money in the account?
What is the change per week in the amount of money in the account?
Answer
From the equation, we can see that the starting amount of money in the account is \(\boxed{450}\) and the change per week in the amount of money in the account is \(\boxed{50}\).
Step 1 ：The equation given is in the form of a linear equation y = mx + c, where m is the slope of the line (representing the change per week in the amount of money in the account) and c is the y-intercept (representing the starting amount of money in the account).
Step 2 ：From the equation, we can see that the starting amount of money in the account is \(\boxed{450}\) and the change per week in the amount of money in the account is \(\boxed{50}\).
