Solution

The correct option is A 3x+5y8=0
If a pair of linear equations are intersecting, then their slopes are not equal.

a1a2b1b2

Given, 2x+4y8=0
a1=2,b1=4

Case 1:
4x+8y8=0
a2=4,b2=8

24=48
Simplifying:
12=12
Thus, 4x+8y8=0 is not the other pair for the lines to be intersecting.

Case 2:
6x+12y8=0
a2=6,b2=12

26=412
Simplifying:
13=13
Thus, 6x+12y8=0 is not the other pair for the lines to be intersecting. ​​​​

Case 3:
3x+5y8=0
a2=3,b2=5

2345

Thus, 3x+5y8=0 is other pair for the lines to be intersecting.
