Question

If 0,2 lies on the line 3x +2y =k, then find the value of k

Answer 1

Answer:

the answer will be

3x+2y=k

3(0)+2(2)=k

k=4

Answer 2

Given :-

(0,2) lies on the line 3x+2y = k

To Find :-

K = ?

Solution :-

》when a point (P,Q) is lies on the ax+by+c =0.

then substitute the points in equation.

sooo 》aP+bQ+c = 0

from question 》(P,Q) is (0,2)

=> 3x + 2y = k

3(0) + 2 (2) = k

0 + 4 = k

4 = k

k = 4
