Data Sufficiency

Lines a and b have different y-intercepts. When line a is reflected around the y-axis, is its reflection parallel to line b?

(1) Line a is perpendicular to line b.

(2) The slope of line b > 0.

Statement 1 : Despite line a being perpendicular to line b, we may have a case (suppose when a and b make 45 degrees angle with the y axis)in which reflection of a is parallel to b and other cases in which reflection of a is not parallel to b.

So, not sufficient.

Statement 2 is not sufficient in itself.

Even if we combine both these statements, we cannot ascertain whether the reflection is for sure parallel to line b.

Hence, option E is the right choice.

my take is E .it can be solved by simple graphs
