The point-slope formula is y-y1=m(x-x1). You will then substitute into this equation. The answer will be y-2=-8(x+3).

Answer:  Lucy pays $ 492.58  back altogether.
Step-by-step explanation:
Formula : Interest = Principal x Rate x Time
Given: Principal  = $425  , rate = 5.3% = 0.053 , time = 3 years
Interest = 425 x 0.053 x 3 ≈ $ 67.58
Total amount need to pay back = Principal + Interest 
= $ (425+67.58)
= $ 492.58
Hence, Lucy pays $ 492.58  back altogether.
