Answer:
A. -4/11
Step-by-step explanation:
Slope formula: 
Using the two points substitute the coordinates into this formula
6-2 = 4 
4 - 7 = -11 
Put 4 over -11 because it is the y value 

 
        
             
        
        
        
Answer:
Step-by-step explanation:
The Beg balance means what she was having initially =$154.90
The pay check and deposit are credits on her account so they were added.
The wig, shoes and makeup she bought were debits, so they were subtracted
Closing balance is the amount left after the debits have been subtracted from the credits

Hello there! I can help you! The formula for compound interest is P(1 + r)^t, where P= principal (initial amount), r = interest rate (in decimal form), and t = time (in years). Let's do this step by step. First off, we add the rate into 1. 4% is the interest rate (0.04 in decimal form). 1 + 0.04 is 1.04. Now, what we will do is raise that number to the 2nd power, because the time that elapses is 2 years. 1.04² is 1.0816. That's that. Now, multiply 7,500 to find the total amount of money. 1.0816 * 7,500 is 8,112. There. Toby's savings account balance in 2 years is £8,112.
Note: To solve for compound interest questions like it, add 1 to the percentage rate in decimal form, raise that number to a power based on the number of years (for example, raise the number to the 7th power if we are looking for the balance after 7 years), and then multiply that number by the starting amount. After you raise the number by a power, there may be a lot of numbers behind it. Whatever you do, DO NOT delete the number. Keep it there and multiply it by the principal.
