The second one is correct
Answer:

Step-by-step explanation:
Look at the picture.
The formula of a slope:
The point-slope form of an equation of a linear function:


We have two points (1, 4) and (-3, 6). Substitute:

If I=P*r*t, we can input 450 in for I, 3000 in for the principal (P, or the starting rate), and 3 for t=time because there were three years, resulting in 450=9000*r. Next, we can divide both sides by 9000 to get 0.05 or 5% as our answer.
