Answer:
if the graph of the equation is parallel line then the form of equation will be
a1/a2=b1/b2not equal to c1/c2
so putting here
3/6=4/k not equal to 5/9
on solving 3/6=4/k
we get k =8
again solving 4/k not equal to 9/5
solving it k is not equal to 20 /9
Step-by-step explanation:
so assertion is wrong k=8
