Formula of a slope is (y2-y1)/(x2-x1)
K is your variable for x2
Substitute:
2- -4 (or 2+4) divided by -1-k
Set the equation and solve for "k":
6/(-1-k) = -1/2
6 = (1+k)/2
12 = 1+k
k = 11
P (-1, 2)
Q (k, -4)
m= -1/2
determine k so that the line through the given points will have slope m.
how do you do this?

Excuse me. k is your variable for x1 the way I set it up.
