Question

Q3 For what value of k do the
equation 3x = y + 8 = 0 and 6x - ky =
-16 represent coincident lines? ​

Answer 1

Answer:

for coincidence a1/a2= b1/b2= c1/c2

so, 3/6= -1/-k = -8/16

or, 3k = 6 , or, k= 2

Answer 2

Answer:

K=2

Step-by-step explanation:

GIVEN LINES

3X=Y+8

SLOPE M1=3

6X-KY=-16

SLOPE M2=6/K

CONDITION FOR COINCIDE LINES

M1=M2

3=6/K

K=2
