Analyzing +4 | -1

If the point

(p, 5)

lies on the line parallel to

y

-axis and passing through the intersection of the lines

2\left(a^2+1\right) x+b y+4\left(a^3+a\right)=0

and

\left(a^2+1\right) x-6 b y+2\left(a^3+a\right)=0

, then

p

is equal to

View answer and explanation

Correct option: B

-2 a

Option B (

-2a

) is correct because the x-coordinate of the intersection point of the given lines, which is parallel to the y-axis, is -2a.
