Each month after the initial month, Cassie withdraws $20 from the account.
Please help

Answer 1

Answer: The answer that is false is “Initially, Cassie has $20 dollars in her account.”

Step-by-step explanation: The reason why this is false is because the first statement that the slope of the line is -20 is true. The formula for slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Next the initial value is 275 because in these problems the y-intercept is technically the starting value in these problems. So since the initial value is 275 the last statement is false.

Have a nice day!
