Question

Let l1 ,y=2Ax+3B+4 passing through the point (1,6) and L2 4x+y=8 be given lines. Find the values of A and B if L1 is parallel to L2

Answer 1

Answer:

A = -2

B = 2

Step-by-step explanation:

As the two lines are parallel so they have the same slope thus

$2a = - 4 \\ a = - 2$

and how putting the values of x,y and a in l1, we get

$6 = - 4 \times 1 + 3 \times b + 4 \\ 6 = 3 \times b \\ b = 2$
