Application +4 | -1

The line parallel to

x

-axis and passing through the point of intersection of lines

a x+2 b y+3 b=0

and

b x-2 a y-3 a=0

, where

(a, b) \neq(0,0)

View answer and explanation

Correct option: C

below

x

-axis at a distance

3 / 2

from it

The correct answer is C (below x-axis at a distance 3/2) because substituting x=0 into the equations and solving for y gives y = -3/2, indicating the line is below the x-axis.
