Line m passes through the points (4, 1) and (7, 3) while line n passes through the points (-3, 5) and (-9, 1).

Which statement accurately describes the relationship between the two lines?
A. Lines m and n have opposite reciprocal slopes so they are perpendicular.
B. Lines m and n have the same slope so they are parallel.
C. Lines m and n have the same slope so they are perpendicular.
D. Lines m and n have opposite reciprocal slopes so they are parallel.

well I think you need to find the slope of each line m and n. 

slope = change in y/change in x

and once you have the slopes, you can then answer the question
