Point (2,-3) is in the 4th Quadrant.

Statement 1 says (-2,3), which is in the 2nd Quadrant, is on line L.

Statement 2 says Line L is not perpendicular. It may or may not pass through the given point.

So, none of the conditions are enough.

Yes, i think additional information is needed to figure out whether (2,-3) is on the line l. Either the slope or equation of the line is required.
So E it is....
