Question

(7) If the lines given by 3x +2ky -2 = 0 and 2x +5y = -1 are Parallel, then the value
of k is

Answer 1

Step-by-step explanation:

For two lines be parallel, their slopes should be equal.

General formula of a line is y= mx +b where m= slope of the line.

Here the lines given are,

3x +2ky-2=0 & 2x +5y = -1

3x+2ky=2 m2 = 2/5

m1 = 3/2k

These lines are parallel, so

m1=m2

3/2k = 2/5

15 = 4k

k =15/4

= 3.75.
