Question

What is 'k' for 5x - 3y = 1 and 2 x-ky = -4 if lines. are paralled.​

Answer 1

Answer:

k= 6/5

Step-by-step explanation:

For parallel lines,

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

According to the question,

5x-3y= 1

and

2x-ky=-4

a1=5

a2=2

b1=-3

b2=-k

(these four things above in fraction is anyhow not equal to c1/c2 so there is no need of this right now for parallel line)

5/2 = -3/-k

, 5/2 = 3/k. ( minus sign is cancelled out)

by cross multiplication

5k=6

k= 6/5
