3y = 4x - 1 and Ky = x + 3 are equations of two straight lines. If the two lines are perpendicular to each other, find K.
A.
-4/3
B.
-3/4
C.
3/4
D.
4/3
Correct Answer: -4/3
Explanation
Grad of 3y = 4x - 1 y = 4x/3 - 1/3 Grad = 4/3 Grad of Ky = x + 3 y = x/k + 3/4 Grad = 1/k Since two lines are perpendicular, 1/k = -3/4 -3k = 4 k = -4/3
Grad of 3y = 4x - 1 y = 4x/3 - 1/3 Grad = 4/3 Grad of Ky = x + 3 y = x/k + 3/4 Grad = 1/k Since two lines are perpendicular, 1/k = -3/4 -3k = 4 k = -4/3THIS WEEK's
