A teacher wants to convert raw exam scores (out of 100) to a 5‑point grading scale using a linear transformation of the form \( \text{grade}=a\cdot\text{score}+b \). The transformation must map a score of 0 to a grade of 0 and a score of 100 to a grade of 5. Determine the values of \(a\) and \(b\).
