The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

m = (y2 - y1) / (x2 - x1)

Substituting the given coordinates of P(2,7) and Q(9,63) in the above formula, we get:

m = (63 - 7) / (9 - 2) = 56 / 7 = 8

Therefore, the slope of the line passing through P(2,7) and Q(9,63) is 8, which is represented by choice B.
