Answer
Interpretation of the slope: If a person's credit score increases by one point, it is expected that the interest rate they pay on a 36 month auto loan will decrease by approximately 0.077 percentage points.
Interpretation of the intercept: Since credit scores have a range of 300 to 850, it would be unreasonable for us to ever substitute $x \approx 0$ into our linear regression equation. As such, for this question, the intercept has no meaning/cannot be interpreted.
