Answer:
Step-by-step explanation:y – y1 = m(x – x1) * substitute (-0.5, 4.1) for x1 and y1
y - (4.1) = (0.8)(x - (-0.5))
y - 4.1 = 0.8(x + 0.5) * distribute the 0.8
y - 4.1 = 0.8x + 0.4 * add 4.1 to both sides
y = 0.8x + 4.5
this is the example hope this helped!

Step-by-step explanation:
Taber invested money in an account where interest is compounded every year. He made no withdrawals or deposits.
The function A(t) = 525(1 + 0.05)t represents the amount of money in the account after t years.

We can just replace the x with 3 to get:
Hence, Wilma has $12.
