Question 666292: Given 2x+3y=8 and 4x-Ky=12, find the value for K so that
1. The lines will be parallel
2. The lines will be perpendicular
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
2x + 3y = 8
3y = -2x + 8
y = x +
Slope is
...
4x - Ky = 12
Ky = 4x - 12
y = x -
...
Parallel line
cross multiply
4(3) = K(-2)
12 = -2K
in a parallel line
...
Perpendicular line
cross multiply
4(2) = K(3)
8 = 3K
in a perpendicular line
