Lilly wants to determine the association between her deposits and her savings account balance. She found the equation y = 75x + 100 for the line of best fit. The independent variable, x, is deposits and the dependent variable, y, is account balance. What does the slope mean in this context?

The slope of 75 means that for every increase of 1 unit in deposits (x), the account balance (y) increases by 75 units.
