Answer:
The value of K is 3
Step-by-step explanation:
Concept :-
Two lines Perpendicular if m1×m2 = - 1
-------------------------------------------------
Slope of x + 3y - 5 :-
=> X + 3y - 5 = 0
=> y = - x/3 + 5/3 (y = mx + c)
We get m1 = - 1/3
-------------------------------------------------
Using property m1 × m2 = - 1
=> - 1/3 × m2 = - 1
=> m2 = 3
Thus ,
=> Y = kx + 7
=> k = m2
=> k = 3
