Question 642383: If (3, k) lies on the line with slope m=-2 and passing through (2,5), find k. Thanks so much!
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
m = (y2-y1)/(x2-x1)
-2 = (5-k)/(2-3)
-2 = (5-k)/(-1)
-2(-1) = 5-k
2 = 5-k
2-5 = -k
-3 = -k
3 = k
k = 3
