Answer:
m - n = 6
Step-by-step explanation:
The formula for the slope of a straight line passing through points (m, 5) and (n, 4) is
4 - 5 5 - 4 1
m = ----------- or equivalently, m = --------- or, in turn, m = ---------
n - m m - n m - n
We are told that the slope is 1/6. It must be true that
1 1
m = --------- = ----------
6 m - n
and so m - n = 6
