Extracted text: Using the fact that the gradient of a line is constant, find the equation of a line passing through the points (5,7) and (9,2) in the forms: (a) Ar + By + C = 0, where A > 0 and A, B, C are integers, and A, B, C have no common factors. Enter your values in the boxes below: A = B = C = (b) y = mx + c, where m and c are fractions in their lowest form. Enter your values in the boxes below: m =
