Question

find the value of k for which the pair of linear equations 4x+6y-1=0 and 2x+ky-7=0 represents parallel lines

Answer 1

Answer:

Step-by-step explanation:

when there is parallel lines, the equation has no solution

a1/a2=b1/b2 is not equal to c1/c2

4x+6y-1=0

2x+ky-7=0

a1=4

a2=2

b1=6

b2=k

c1=-1

c2=-7

a1/a2=b1/b2 not equal to c1/c2

so 4/2=6/k

6/k=2

2k=6

k=6/2=3

k=3

hope this helped ;)
