Keep it consistent!!!
----- eq (i)
y = mx + 1 --------- eq (ii)
4 = - 3m + 1 ------ Substituting 4 for y and - 3 fox x in eq (ii)
4 - 1 = - 3m
3 = - 3m
m = , or

----- Substituting 4 for y, - 3 fox x, and - 1 for m in eq (i)
4 = - 2(9) + 3k + 1
4 = - 18 + 3k + 1
4 = - 17 + 3k
4 + 17 = 3k
21 = 3k
k = , or
