Tina has $600 in her bank account when she starts withdrawing $50 a week. What is the slope in this problem?
To find the slope in this problem, we need to identify the relationship between two variables. In this case, the variables are the number of weeks Tina has been withdrawing money and the amount of money she has left in her bank account.
Let's set up a table to analyze the relationship between these two variables:
Weeks (x) | Amount of money (y)
---------------------------------
0 | $600
1 | $550
2 | $500
3 | $450
4 | $400
...
From the table, we can see that the amount of money in Tina's bank account decreases by $50 each week. This means that for every week that passes, the amount of money decreases by a constant amount of $50.
The slope represents the rate of change, which in this case is the decrease in the amount of money per week. Since Tina's bank account decreases by $50 each week, the slope is -50.
Therefore, the slope in this problem is -50.
