For each linear relationship identify the independent and dependent variables. Then calculate the rate of change / slope for each situation.
Christopher has saved $65 after 3 weeks and $98 after 6 weeks.
savings is dependent on weeks
(98 - 65) / (6 - 3) = $11 / wk
Thank you
To identify the independent and dependent variables in this linear relationship, we need to determine which variable is being influenced or affected by the other. In this case, the amount of money saved is being influenced by the number of weeks passed.
So, the independent variable is the number of weeks (x), and the dependent variable is the amount of money saved (y).
To calculate the rate of change or slope, we can use the formula:
Rate of Change = (Change in y) / (Change in x)
In this scenario, the change in y is $98 - $65 = $33, and the change in x is 6 weeks - 3 weeks = 3 weeks.
Rate of Change = $33 / 3 weeks = $11 per week
Therefore, the rate of change is $11 per week, which means Christopher is saving $11 per week.
