45,

m = kh

405 = 9k

Thank you!!! and while you are here, if two distinct lines in a system of linear equations are parallel, they:
A. have the same slope and no solution
B. have the same slope and an infinite number of solutions

Well, they're parallel so they never intersect, so they have the same slope and no solutions :)
